Huge thanks to Charles for coming over and helping me get the tank back in. It feels indescribably good for her to run under her own power with a complete fuel system. I'll circle back to my fuel tank restoration thread with an update. But in brief: cut tank open, bead blast clean, drill spot welds for screen canister, cut suction pipe to access screen, remove screen, Red Kote everything, reassemble, slosh more Red Kote around seam, bead blast outside, paint. Easy, lol.

So we worked on the 280z some more yesterday. Put the restored tank back in it and added some fuel. Fuel pressure came up after cranking but wouldn't come up in the "On" position. Cranked up first time. Bolted some wheels on and went for a quick spin!! 20250613_194943.mp4Don't know how to add a video...??

I'm all LED except for the dash. I used a couple of these from Amazon for blinkers and emergency flashers and they've worked just fine since I installed them back in 2017.

Haven’t solved it yet. Having work done on the house and can’t get my car out of the garage. Hoping in a few weeks I can look at it again

YES!! Glad to have you back :)

Wow! 😝

I’m not sure, maybe you’ve worked this out while I’ve been in exile. I have to assume stock L-Jetronic EFI? If so, open the air flow meter and tighten the spring a bit.

Miss me Steve?

So did you replace just the electrical part and save your keys?

Installed the new switch and she's back to starting as she should. As a note to others, there is a short video (Google) on how to go about replacing an ignition switch on an old Z. I found this was helpful.

Take a picture of the ASAHI stamp on the window, and post it here. The dots tell the dates.

Got it, I'll give it a look. Thanks!

I mean both, but better to remove wipers and pull cover. I had this exactly problem. We welded a patch in the floorboard at that spot to repair it. Also repaired the holes in the cowl around the air intake. So the water was leaking down the inside under the carpet so you couldn't really see it.

Do you mean pull the cowl plate off and look or looking up from the passenger footwell?

Check the area under the cowl cover where the wiper motor is. The air intake tends to rust out under there allowing was to run down the firewall to the very spot where your rust hole is. If that is rusted through you'll need to repair that as well.

Some options to investigate: https://upgarageusa.com/pages/nos-parts-we-have-instock-for-1969-1995-z-cars https://vintagerubber.com/datsun-240z-260z-front-bumper-guard-over-rider-strip-kit-69-72/ https://jdm-car-parts.com/products/front-bumper-over-rider-vertical-strip-set-for-datsun-240z I believe I have a spare set of aftermarket ones as well - I think of decent quality. Let me know if you would like to see some pics of them.

I just switched to OEM flasher relays and tried it with the LEDs still installed. No change. The lights come on but don’t flash. Then I pulled the LEDs and put incandescent bulbs in, which totally fixed it. So it’s the flashers and/or the LEDs and not the wiring. I am going to try swapping the wires over the weekend and putting the LEDs back in (no time right now. Work deadlines). If that fixes it I’ll just leave it like that until I get around to buying new relays.

I used the two prong electronic flashers for a while after converting to LEDs. I found that some of them had spotty performance. After that I switched to 3 prong flashers and grounded the third prong. That has provided reliable performance for years.

If someone is looking for an original Bosch version of the 280Z auxilary air valve here is one in NOS condition. Its for a 1976 Porsche 924, but it's a very similar system.

I haven't messed with that flasher, but I have a couple ideas... First, yes, it is completely conceivable that the electronic flasher is susceptible to polarity issues. I'd certainly make sure you have it wired with the load on the "L" pin and power on the "+" as shown in that diagram. I found a couple other pics of that flasher from other vendors, and the mounting tab is not electrically connected in any way. So forget about the below. Second, does that "two wire" flasher need to be mounted with it's tab attached to ground? In other words, is it really a three wire flasher, but they don't count the third wire because they might be making a ground connection through the mounting tab? Just some ideas.

They definitely were. Did that cause the brakes pads to tighten on the rotors? There was some brake dust everywhere. I ended up doing 3 things at once, flushing the brake fluid. Disassembled the calipers, and repack and set the wheel bearings correctly. The wheel bearings heating up may have caused air in the brake fluid to expand and tighten the brakes, I don't know. I just finished it off by adjusting the pedal to the floorboard distance, it was 7", now it's 8". Same with the clutch pedal, it was an inch off. Then set the master-vac push rod length to 3.5mm below the flange surface. I had backed everything off while 15 miles away trying to get home, not knowing what was going on. Things are looking good now.

That’s a first for me to hear. Not sure how that explains the heat problem you are describing?
