I don't think you'd want to leave the tank to vent in any enclosed space, like a garage! When I did my tank I drained it (discarded the fuel at the local hazardous waste facility). Put the drain plug in and pulled the tank and sealed over all the vents, gas in and out tubes and filler port. This was 5 years ago, but my friend walked me through how to clean the tank and prep it for sealing out in the driveway. Once all that was done the tank cured for maybe 2 weeks and then put it back in. Probably another couple of weeks before I was ready to put any gas in. It's been fine ever since and has had nothing but ethanol free fuel.

Questions... 1-How did you mount the hoses for bypassing the metal fuel rail? 2- Rather than dead head... Why not a short piece of piping in the hose on the return side (after the carbs) that had the correct restrictor orifice size that Datsun crimped in the end of the return line of the metal fuel rail to even out the fuel pressure?

Here in Utah where we regularly see 90+ in the summer I've been running Driven (Joe Gibbs) HR1 15 / 50 and have had no issues with great oil pressure.

Very nice car! not that it would make any difference, but I think the wheels are Rota RB's, not RKR's.

Sounds like everything you're doing should be raising the boiling point of your coolant which I believe is a good thing. Once coolant starts boiling in the block the air bubbles touching metal cannot pull heat from the metal anymore which can lead to bad things happening. Didn't you say you were running a 190*F TStat? You could try changing that out for a 160*F TStat and see if that helps bring your temps down. From what I've read here you would want the TStat with the centered valve rather than the one with the smaller offset valve.

With Dallas being fairly close to sea level the boiling point of water is right about 212*F. Based on that you've got about 15*F to play with if you ran straight water. Then mix that with antifreeze which has a boiling point of around 387*F a 50/50 mixture would have a boiling point around 223*F so you would have almost 30*F to play with before you boil. You will have a little more room due to the cooling system being pressurized which will raise the boiling point temp even more. One other little thing is that water typically is the best at heat transfer where the 50/50 water / antifreeze may not be quite as good at transferring heat from the engine. This is kind of just off the top of my head. I'd bet @Captain Obvious or @siteunseen would be able to provide more and probably better enlightenment! My thought is you should be okay at 195*F and I'm sure as soon as you start moving it will come down.

Don't know if they're the same bulbs as a 240Z. I used this LED in both the dome and map lights in my car. DE3022 CAN Bus LED Bulb - 18 SMD LED Festoon - 31mm - 90 Lumens | Super Bright LEDs Here's a list of some of the other LED's I used and where they go on the car.

I had the same rack on my 73 Z but I put it on the drivers side.

I really appreciated not having a switch when my clutch slave failed away from home. Start the car in 1st gear, shifting is easy enough doing RPM matching. Shut the car off at a stop, put it in 1st and start the car to get going again.

Langes were notorious for what we called "Lange Bang". My experience with them was a long ways from soft inside! Nordica's were much more comfortable. I'd agree with the Head Vectors and Scott poles. Worked at Watson Shelter at Alta for a season back in about 1970-71, greatest snow on earth.

Once upon a time on my old 73 240z I put Michelins on my car after I wore out the factory Toyo's and with them came a steering vibration at about 60+MPH. I tried rotating and rebalancing and nothing would correct the vibration. After putting up with it for a couple of years I replaced the Michelins with BF Goodrich Radial T/A's and low and behold the vibration was gone!

I'm with Steve, those seatbelts aren't stock, on a stock 73 car the shoulder belt would be a separate piece that clips into the lap belt if you want to use it. And I also went with the Roadster seatbelts with the retractor connected at the roof location.

Can't answer that since I went electric fans and as you can see from the picture the tabs on that electric fan shroud were a perfect fit on the engine side of the radiator.

I did the 3 row aluminum from MSA. No tab bending, just bolted right in with no adjustment on my 71 240Z. Motorsport! Aluminum Radiator, 3-Row, 70-8/74 240Z-260Z - The Z Store! Nissan-Datsun 240Z 260Z 280Z 280ZX 300ZX ( Z31 Z32 ) 350Z 370Z Parts I've had no trouble with it since I put it in.

So sorry for your loss! Sounds like you're working through it and that's a good thing. Congrats on the new house and man cave. That dash does look rough, are you reskinning or replacing from Vintage Dashes or ...?

here's 205-60-15 which calculates to 24.67" tall

It sounds like the fuel regulator my dealership used back in 1974. When the dealership did the electric pump on my 73 they put a round adjustable, shinney silver fuel regulator between the Engine bay fuel filter and the mech fuel pump which they left in the circuit. The regulator was maybe 2.5 - 3 inches with a dial on the top with labeled detent stops labeled something like 1 through 6.

Or... To attach the snowplow blade. 😁

When I put my car back on the road in 2017 after a long nap I cleaned and lined my tank and replaced all rubber fuel lines with E85 rated Gates lines. My carbs were refurbed by Z-Therapy. I contacted them about E fuel and they said they've seen no trouble in their soak testing. I do have access to ethanol free 91 octane so that's what I run and will run as long as I can in my Z and my wife's truck. Many local Maverik's also sell ethanol free 88 octane. I also use the ethanol free for all my yard equipment. One of the big things I notice is how much easier things start when using ethanol free gas.

I only have the urethane air dam and no rear spoiler. My experience before the air dam was that the front end starts to "feel light" at 85-90 MPH. With the air dam it feels much more stable at even 100+ MPH.

I'm a short timer, only been around here since 2017. I think I was originally on IZCC (#2831) back in about the 1999 time frame and then updated my IZCC info in 2017 when I got my current 240Z back on the road after it had a ~14 year nap in my garage. I have been a continuous 240Z owner since 07/20/1973 when I bought my '73 240Z.

I thought this was a change and the early carbs had the same needle valves front and rear. Don't know if the change was implemented at the same time the carbs went from 4 to 3 screw. Of course I may be up in the night. 🤪

Yes, Hill AFB is still active. The f16's have been replaced with f35's. I golf on a course that is just on the east side of Hill, man those planes are loud but very fun to watch. There's a gal that heads up the f35 demo team and what a gas to watch when she's out practicing! I do know how hot you get in the summer. I've had flights delayed out of Phoenix because of heat making the air too thin for lift on the wings. I spend the winter in St George and sometimes I'll come down for golf in the summer because prices are low, can walk on any course and the courses are in great shape getting them ready for the winter (much the same as in Phoenix). I have a good friend in Idaho Falls who's an old VW person. I pass through there every year on my way to Island Park for an annual fishing trip with some old work buddies.
