If it's leaking coolant above the spark plug at the rear, that's #6, you may have a cylinder head gasket leaking. You could very carefully re torque the head bolts and maybe stop it but if you have to have the head gasket replaced, that is a major job unless you're a mechanic, shade tree even. If I was you I would start a new thread topic on your problem, you'll get more responses. Good story about your history with the Z. Cliff

The distributor is what we call the "dizzy", it has a cap with 6 spark plug wires going around the outside edge and the 1 in the middle goes to the coil (beer can looking thing on the driver's side firewall). Taking the center wire from the distributor cap, HT lead (high tension), and holding it about a quarter of an inch away from something metal it should make a pop sound and you should see a small "lightning strike" from the metal inside the rubber boot to the metal you're holding it next to. Do this in the darkest light you can or you won't see it. If you're feeling sparky, just hold it and let somebody crank over the car. It'll shock the crap out of you, but you'll be okay. The one going off to the right in this picture,

I'm pretty sure the hose from the tank to the pump is 3/8" (10mm), and can be the cheaper low pressure fuel hose. Everything from the output port of the pump is 5/16" (8mm) HIGH PRESSURE for fuel injection, more costly but you've got to have it. You'll see the difference.

You can buy from Advance online then use a coupon code and save some pretty good money.

It goes before the pump. Between the tank and the pump. Read this, http://atlanticz.ca/zclub/techtips/fuel/g3filter/index.htm

Holy moly! The OE pumps are $400 now. I paid $250 for my Bosch a few years ago, now they're Beck Arnely. http://www.amazon.com/Beck-Arnley-152-0253-Fuel-Pump/dp/B000CB32QG/ref=au_as_r?_encoding=UTF8&Make=Nissan%7C67&Model=280Z%7C874&Year=1977%7C1977&ie=UTF8&n=15684181&newVehicle=1&s=automotive&vehicleId=2&vehicleType=automotive

From the searches I've done, they're all made by these folks; http://www.accmats.com/ Zcarsource is as cheap as anybody else I've found. I don't know about doing the seats yourself, it's pretty involved from what I've read. http://www.classiczcars.com/topic/44331-diy-how-to-recover-your-z-seats-lots-of-pictures/ I've bought 2 more Zs and the carpet fell to the bottom of the 280s list.

Anybody ever used this stuff?

I've used a siphon gun in the past with coal slag, it gives a rougher finish but works pretty good. It's so damn humid down here the siphon would stop up every other minute. I wanted something a little less abrasive for a smoother look. I'll be clear coating the aluminium parts with a high heat clear from Eastwood Paint and my steel parts with black satin finish. Drive Shaft, transmission mount etc. Arrrghhh Cap'n!!!

If you can drive it and it not feel like the front ends gonna twist off I'd buy it. Those early ones are scarce as hen's teeth. Part it out at the worst. Those holes may be a bargaining point. $5,000 !!!

Have you tried routing your AAR hoses like the later '78s? That made a noticeable difference in warm up on my car. It pretty much did away with the 1200 rpm when cold.

It comes with a hood. I chose not to wear it while I was dialing in the settings for the first time. Yesterday I wore the hood and a lightweight pair of summer pajamas. Pretty damn funny looking but it was so much better than the day before. I've still got crusty eyes in the mornings. I've found an eastwood product for raw aluminum, Diamond Clear satin for $40 per quart. 300 degrees. I'm gonna coat everything I blast, claims to be fuel and oil resistant. Thanks for the warnings, silica sand is the worst, I've read about. Cliff

Here's a very good thread on "waking the sleeping beast". http://www.classiczcars.com/topic/21063-waking-the-sleeping-beast/ Carl Beck's post #8 Welcome to the forum, sounds like you have a head start already. "Sorry for so beginner questions but I do not want to forget anything and take a risk of doing more harm than good."

Sounds like your aftermarket pump is shot.

Positive is smaller on mine. Just checked.

I bought the one for a four door Camry, it's huge. So at least a size smaller, maybe two sizes?

I been down that road also. I ended up replacing everything except the hard fuel lines from the rear to the engine bay. If bought another one today the first thing I would do is put a clear filter between the tank and the fuel pump. Fram G3s are $3. Here's the details; http://atlanticz.ca/zclub/techtips/fuel/g3filter/index.htm You'll be able to see if you have particles in there from a trashy tank. You probably need a $10 fuel filter up front behind the radiator on the passenger's side fender too, it can't hurt if you haven't already replaced it.

All you have to do is kick it when it gets low and it'll spray for about another minute, repeat. Mine is new so I can't say what'll it'll do next time but from my experience the last 2 days is that if you fill it half way it'll spray heavy for a few minutes then it starts pulsing for a few more minutes then it's just air, that's when a gentle kick gets it spraying again. I'd say it's about a fourth full or less when you need to start shaking or kicking. Next time I'll tie a rope around my knee and the top handles, sorta like a one man band will do. Mine only needs shaking when it's low on media, but for the price it's not perfect, although I didn't have any "crisis" moments. Results: This is what's left,

You need "atlanticz tech tips". Google it and look under "efi and fuel". I'm using my phone now, sorry I cant link it for you.

That's funnier than hell! I put one foot on top and sit on a milk crate. Thought about using some rope. Like I said, it takes patience! Back to it.

Those are nice! Dear Santa...

I got an AutoCraft like this for about $65 for outside. Universal sized so I got the large, it fits all my cars. I leave my 280 outside and it keeps it dry. EASY ON THE WALLET, for sure.

I hate to be lazy, I know it's somewhere in these 24 pages, but what'd you do for the outside engines bolts? Buy new or have your's replated? Thanks for any help, Cliff.

I was going to buy a small igloo styled tent, $25 from Academy Sports, and sit inside to keep the mess down but to be honest it's not as bad as I thought. I'm okay losing a little. I put the parts inside the biggest plastic storage tub I had and put that in the middle of a 10x12 tarp, fold the tarp and poured that inside the tub. Scooped it out and put it back into the sandblaster. The blaster sprays my particular media for about 1 minute, then you just shake it back and forth and it starts right back up. It doesn't make any kind of "floating" dust, to my surprise. The heavier stuff like coal slag and sand will wear it out and make a bigger mess. This one is for parts that'll fit inside the plastic tub. I'm using 1 lb Cool-Whip bowls for scooping and figure I lost between 1 and 2 pounds (very little). So the results minus the PITA, plus I'll have to replace the valves sooner or later, I'll say 4 out 5 stars for the money. It requires some patience but beer helps.

It says glass beads but it's more like pulverized glass, 80 grit. http://www.tractorsupply.com/en/store/black-bulltrade%3B-no-80-grit-abrasive-glass-beads I did it in a big plastic tub and only lost a few pounds. Did it on top of a tarp too, folded it up and poured that into the tub then filtered it back into the pot. I think there's a pound in my eyes and hair. I'll wear the hood tomorrow for sure.
