The original pump includes an inlet strainer, but I don’t think the O’Reilly’s E16078 has one. In principle it’s the same style as the Bosch 0580 254 044 that replaced the factory unit. If you want to add a pre-filter, you can install two 5/16" filters in parallel to avoid fuel starvation and prevent cavitation in the pump. Their only purpose is to protect the pump, the filter up front will protect the injectors. 280 Series Fuel pump Alternatives Rev 1.pdf

My new neighbors are smoking turkey legs today. I'm about to go introduce myself.

Happy Thanksgiving to the Z family!!! I am grateful for this group!

Use the wheel to get close and the brake lever for final adjustment. Tighten the wheel until the drum barely goes on, then pump the brake lever a few times. If the self-adjustment is working the lever will only come up about half-way. As you drive the car occasionally you'll notice that parking brake lever got tighter as the wheel moves a notch.

🤣 OMG... I used to do that... Thank goodness I haven't seen a phone cord in decades!

Just got the harmonic balancer Back. Looks really good. Namerow asked for pictures.

Have you seen this? Inside a stranger's house with my parents and I was unwinding their phone cords.😇

Also check the vent hose seals from the fuel tank where they come through the floor. The grommet at the license plate light where the wires pass through the rear pan. The seal around the filler neck and the grommet at the drain for the radio antennae

The aftermarket hardware kit at O'Reilly's has 8 of those retainer washers rather than 4 retainers and 4 cup washers. One on each side of the spring to keep it centered and in place - would work.

Happy Thanksgiving!!! Fire up those ovens... I'm smoking some turkey this year... ;)

Now get some sleep. 🙂

Okay, so I've received various plugs and set screws from both McMaster and Bel-Metric. I ordered 1/8 and 1/4 NPT, 1/8 and 1/4 BSPT, M12 x 1.50 straight thread and M12 x 1.50 tapered thread, and I am still a bit confused! I won't hold you hostage until the end, I'll give you what I THINK the holes were from factory, and then I'll provide some pictures and notes from my "testing". I think the factory balance tube (US market 240Z) came with 2 ea. - 1/8" BSPT and 5 ea. - 1/4" BSPT holes BALANCE TUBE 1/4" BSPT HOLES it was clear to me that 1/4" NPT is too big, couldn't really even get a thread to start, so it makes sense that, 1) One COULD force 1/4" NPT into the holes in the soft aluminum and create some sort of "seal", and 2) a hole that had been "buggered by a previous (or current!) owner could likely be salvaged by tapping to 1/4" NPT. The 1/4" BSPT plugs I have encounter resistance at 1-1/2 turns and are fairly tight at 1-3/4 - 2 turns. This leaves them sticking out farther than I would like for a clean, plugged look as I would like them to be as close to flush as possible. The M12 x 1.50 straight thread, socket set screw I tried fit very loose initially, and threaded quite a ways in (farthest of the three options I tried) before finally hitting resistance. I feel like it MIGHT have finally created a "seal", but not ideal in my opinion. The M12 x 1.50 TAPERED plug encountered resistance at about 3-1/4 turns and was fairly tight at 3-1/2 turns in. This left it pretty close to flush to the surface and provided a good seal and I think this is what I will be using to plug 1/4" BSPT holes. (see pictures below) BALANCE TUBE 1/8" BSPT HOLES it was clear to me that 1/8" NPT is too big, couldn't really even get a thread to start, so it makes sense that, 1) One COULD force 1/8" NPT into the holes in the soft aluminum and create some sort of "seal", and, 2) a hole that had been "buggered" by a previous (or current!) owner could likely be salvaged by tapping to 1/8" NPT. The 1/8" BSPT plugs I have, encounter resistance at 1-1/2 turns and are fairly tight at 2 turns in. This leaves them sticking out more than I would like for a clean look (see pictures below) now I want to experiment with M10 fine thread (both straight and tapered) in the 1/8 BSPT holes INTAKE MANIFOLD WATER HEATING HOLES The outside (inlet and outlet) holes come from the factory with 1/4" BSPT holes Again, the 1/4" BSPT plugs don't thread in very far and sit proud. The M12 x 1.50 TAPER thread plugs thread in farther and sit pretty flush for a clean look. the inner holes (two holes on the inside of each part of the two-part manifold that connects the manifold halves with "bushings" and metal tubing) come from the factory with M16 x 1.50 STRAIGHT thread. I have some M16 x 1.50 straight AND taper plugs coming to try in those holes. I'm now thinking that a straight-threaded plug with a low head and Loctited, may be the ideal ticket for this hole since there is a machined spot to accommodate a bolt head. Heck, any old M16 x 1.50 bolt will work here! Keep in mind that these holes, if not being used (not connected to water lines), can stay open, they do not need to be sealed/plugged, as they will not affect anything other than keeping the intakes warm on initial start-up in cooler weather/climates. I just want to plug them for aesthetic purposes. Here's some pictures to clarify my rambling!

I get a kick out of a big horn sound coming out of a weee Z car. 😎

Good question. Pull the parking light fuse and see if things change.

To recap...I was looking for suggestions on replacement horns for now until I get around to rebuilding the original ones. I ended up buying and installing these from Z Car Depot: https://zcardepot.com/products/horn-set-hi-lo-240z-260z-280z-510?variant=50610208964920&currency=USD&utm_source=google&utm_medium=cpc&utm_campaign=google%2Bshopping&gad_source=1&gad_campaignid=17820837536&gbraid=0AAAAADgHqXssZ64ffuRLMdHFQA1WVqNee&gclid=CjwKCAiA86_JBhAIEiwA4i9Ju_aM-ViE06tUtzcGp1fUrYiM7OyJd_3WeMCCfgkuDa7cRHrPUPNNsBoCRM4QAvD_BwE They do the trick. Not sure when I'll get around to diving into rebuilding the original ones, though for now I can still drive around and let people know I there. :)

I've been using a set of FIAMM air horns for about 50 years, very Euro and VERY loud!!! 😲

Absolutely! Will take me a little while, but the quality and sound were great on the test run!

Steve, though I’m sure you’re not surprised, it worked! Thank you!

It will even both sides out. It affects the adjustment of the shoes so will affect the brake pedal. Can't remember for sure but I think that you will also feel the brakes apply a little higher on the pedal after a notch gets taken up. It's one reason that seems rational for converting to disc brakes if you're in to precise brake performance. Should emphasize though that you need to be sure the parts are clean, lubricated, and not worn, in order for the system to work correctly. You can test it with a drum off by pulling the cable by hand and watching the parts move, I think.

It's there strictly for water management (by design, it can't contribute to sealing off exhaust gases from the cabin because covers only the top and sides of the hatch opening, while remaining completely open to the outside at the bottom). If your Z is a later-model 240 (where there are no vents on the lower hatch surface), the most likely culprit will be your main weatherstripping ("the large weatherstrip that's been installed years ago"). It may have lost some of its original shape after years of living 99% of its life in a crushed state while the hatch is closed. IIRC, some owners also found that the gasket around their taillights housings had deteriorated, allowing exhaust gases to enter the cabin through the rear panel. If your Z is an earlier-model 240 (vents on the lower hatch surface), that's a whole different (and more challenging) ballgame. There are several threads on the CZCC site that discuss problems (several) and remedies for this design.

That's the fuel damper. It absorbs pressure pulses, from one end or the other. Not much to it and they seem to survive without problems. Don't forget that pressure after the pump is at least 36.3 psi. Those small plastic filters aren't rated for that. I made a loop in my fuel line after the pump to solve that sharp bend problem.

I'm fortunate that I have multiple daily drivers, rather than just one. In summer time the 240Z is my daily, along with a R53 Mini Cooper S, a 1999 Mazda Miata Sport, an Aston Martin V8 Vantage and a Toyota GR86. For load hauling and snow runs the Subaru legacy wagon gets the nod. Between my wife, my son and myself we need at least 3 dailies!

Just got this back today from Sanderson's headers South Francisco it's ceramic coated inside and out $150. Nice people quality workmanship

My daily driver.

I have used an epoxy product from Caswell to coat a tank. It's very thick and would deal with pinholes pretty well. I suspect that tank will have quite a few pinholes once it's properly cleaned. It might be hard to do in an apartment setting...

I made mine as tight as I could on the slack side, the one that curves. I pushed the tensioner in all the way and put a zip-tye on it then pushed the curved guide as tight as I could and tightened it down. For some reason I'm thinking there's a white plastic washer that goes on the tensioner between the housing and the pad but it's not visible in my picture. Maybe you can confirm that and don't forget the oil slinger that goes on the crank nose.

Seek and ye shall find! I was able to find it and jumper the connection. It was really burried at the back. For others coming to this thread, when looking at the two wire bundles from the passenger side it's connected to the one on the right. It splits off from that. (see pic with finger pointing to it) Just grab the smaller taped up bit coming off it and start pulling. The Nismo pump is a bit noisier than I'd like but I'm really happy none the less. Initial pressure on start up is around 6psi and then once it warmed up it dropped to 4 to 4.5psi. I've moved the red wire from the + side of the coil to the ballast and it runs. But, I've currently got a intermittent misfire on two cylinders. Number 2 and 5. I found them by attaching the timing light plug wire connector to them and the light flash wasn't consistent. I've ordered new NGK plug wires, plugs, cap and rotor. I'm not sure of the cap and rotor though. I went ahead and assumed they're for an L28 though I could be wrong. How can I identify the difference between a L24 distributor and one for an L28? I'm guessing they're not identical. I know the 240Z had points and the 280Z didn't. As the car has a L28 from 2000 I'm assuming they also threw in a later distributor with the Pertronix. I pulled the plugs and they were really sooty. I cleaned them with a wire brush and that didn't really help. I'm wondering if it's my ignition or if I'm just running super rich. Both of those are on the most direct line from the carbs and I'm assuming would be getting a more fuel than the other cylinders to their sides. Brakes also need to be fully bled as I've installed the 8.5" booster upgrade from JDM-Car-Parts and new master cylinder as well. So it drives and stops and can be driven around a parking lot or paint shop if need be.

OK. Just got the last of the plugs in. I like the M16 x 1.5 low headed plugs to fill the inside ports of the intake when one has removed the water heating. Purchased them from Belmetric.

I really appreciate that thank you. I was certain I did everything right I just didn't get to number (11) eleven. I saw your 2019 post and your mathematical computations Cheers

And the magic number is 11 rotations of the cam, or 22 rotations of the crank. https://www.classiczcars.com/forums/topic/62752-bright-links-on-timing-chain-line-up-every-11-rotations/

NECROPOST ALERT!!!!!!!!! A broken hi- lo beam switch housing circuit board CAN be repaired so it will work correctly without the switch butterfly moving out of position between switch plunger detents. One just needs a steady hand and more importantly, a command of various epoxies and repairing compounds available retail to ascertain what is most apropos for your situation. Also, depending on the severity of the circuit board damage, the repair may necessitate making the circuit board unremovable from the housing. It's a Datsun. there is always a way...

The fit up looks good!

I thought it would be prudent to assemble what I have so when I do the other side floors and such I have my gaps set on the drivers side already . The tunnel is pretty flimsy at this point . The passenger side just scares me as far apart as I have it .

@Terrapin Z probably has some good quality used ones.

The FSM describes how to adjust the horn sound and its actually very simple (screw on the back with a locking nut). Not saying they'll sound like a Jag, but altering the way they sound is possible. I believe each horn is set to a different tone.

Have a nice day, people!

Here's the start. Notable that there's no way for too much voltage unless there's a problem with the voltage regulator. I think he meant current. The best way to handle disparaging comments is with postitive comments. Take the high road.

It was nice to see truthful information about this issue from another experienced person to cut through the character assassination that passes for knowledge from some of the members of this page.

It is also important not to mix adjusters from one side to the other, as I believe they are handed

I hope you have access to a lift, if not get the car as high as you can and from previous experience have someone to assist. I have the same set on my car. They are close but far from perfect. It’s tight underneath there. Biggest problem I ran into was getting them past the undercarriage near the rear passenger wheel where they shoot straight up and over. It can be done obviously. Wish I had done it on a lift it would have made it a lot easier. Also it’s going to arrive in a tall box where you have to use a tubing tool to straighten out the long straight lines. They will come marked at each point of the run. Purchased mine on Amazon.

Mine were more crud from leaving old gas in them for too long. The tanks were good and solid after I pressure washed the outside of them. That muriatic acid made the inside like new but after sloshing around for 5 minutes I had to pour in about 3 gallons of mixed ahead of time baking soda and water to neutralize the acid then emptied that into an empty 5 and killed a lot of ant beds around my property. Then the acetone to remove the water, quick hit with the leaf blower and then the Red-Kote. Sloshed that around completely covering the tank and let that drain out into another 5 then direct sunlight for 30 minutes, then another round with the leaf blower. Then I put that bitch on a shelf and got drunk. It was very nerve wracking for this 'ol boy, but when all was said and done I was and still am proud of what I did. You see, I hate following directions.

I just used the link that Zkars provided in his #2 post. The Gyraline website currently features their Black Friday deal and offers the option of having the price displayed in the currency of the customer's location. IIRC, I had to select the 'G1' (iPhone) or 'G2' (android) product first, add it to my Cart, and then go to the Cart to see the price. I tried this posing first as a Canadian customer, and then as a American customer. The quoted price in Cdn $ for a Canadian customer was significantly higher (numerically) than that for an American customer -- but maybe that was purely the result of performing a currency conversion. Additional costs for shipping/handling and duties/tariffs might get tacked onto the Canadian price afterwards and not become visible until later in the check-out process. A quick internet search indicates that Gyraline was incorporated in Delaware in March 2024, with operations based in California and Texas. I have no idea where they do their manufacturing. Given the the nature of the design and the relatively low production volumes, it could be as simple as contracting out to a US-based additive manufacturing company ('additive manufacturing' = commercial-grade 3D printing).

I have heard it said that the bright links of the timing chain will "line up with the timing marks ever now and then" when you spin the engine over. Well... I'm here to put a number on it and that number is eleven. I lined up my timing marks and then rotated the crank to see how long it would be until the marks lined up again, and the answer is that they line up every eleven rotations of the cam (twenty-two rotations of the crank). Not being satisfied with only experimental results, I counted teeth and links and stuff. There are 20 teeth on the crank gear. There are 40 teeth on the cam gear (makes sense since the cam spins at half the crank speed). There are 110 "teeth accepting holes" in the chain. The common multiple (modulus maybe?) of all of those numbers is 440 and it takes eleven cam rotations or twenty-two crank rotations to move 440 link holes. The links of the chain will line up in the same position every eleven rotations of the cam. And because everyone likes pics... Timing chain and pulleys:

Bright ideas come from bright people! Thanks!
