I appologize in advance for posting this here, but this is time sensitive and I don't know if an entry in the classified section would show up on the front page or not.

The tank is for a good friend of mine here in Ventura, Ca. that has no access to the internet and needs a tank now. Any and all help is appreciated.

Hi guys! Im having trouble with my Z at the moment. A couple of problems at once but managable and one problem Im not quite sure how to fix other then some extensive cleaning of the fuel system or ignition system. The Problem: :pirate: Starts up fine like it always has but recently it sputters like its running on 3 cylinders and is blowing black smoke from the excess gas not being ignighted like it should be. The car lacks power BIG TIME and is not safely drivable at the time. The other problems Im fixing with it are the old heater hose from the fire wall to the back engine S shaped hose went out and started leaking anti freeze while I was driving and made the ca…

Where does the vacuum line from the BCDD go to? I think it's the thermal vacuum valve, but I lost my notes on that and I can't find a picture of the BCDD circuit. thx

If you want to remove the cold start injector from the F/I setup, would you remove the air regulator and thermotime switch as well? Also, if you were to do this what do you do with the electical connectors so that it doesnt mess with the computers mixture readings and what not. What is the standard precedure for doing all this. I'm getting a cutom fuel rail and i want to elimate the cold start Injector because i think its giving me rich conditions, plus i live in So. Cal. Thanks for your help Steve

.....with my '76 280Z? I've read where some have been successful, but didn't list the type of tank used. I've run out of ideas on finding a useable replacement OEM tank for it. Thanks in advance, Spdloader

I've seen several beautiful Z fuel injected motors that are super clean and simple (like my brain!). Many of the hoses and smog paraphanalia are removed. Does anyone have advice as to what is extranious and can safely be removed? Will motor run better? Great site. Cheers to all. David

I have a donor 280z that I recieved for free, and I would like to transfer the fuel inj. system to my L28 240. The thing is that it has sat for 8 years. I just need to know what all to pull from the 280 and what to clean it with. I'd assume carb cleaner in the AFM and fuel rails. Can you clean the injectors? Also, what exactly do I need to pull from the 280? What I hope to end up with in the near future is a 240z turbo. Thanks, Brian S.

Just a info request for tank straps length. Would like to compile a list of strap lengths for all model years. (240, 260, 280) Measurement should be taken from front edge of strap bracket (Where the "J bolt" passes thru bracket) Please label "Left" & "Right" side. See enclosed picture for reference. From what I can gleam from various posts these usually break when trying to get the J bolt nuts off or are usually in somewhat poor shape after many years of use. Checking into fabricating some.... Thanks... webdawg1

Anyone out there in Z land have any idea what the stuff was/is that they used to seal up the electrical connections (Positive/Negative terminals) on the electric fuel pump. (75-78 FI models) Looks sort of off-white or a light pink when you start breaking off pieces of it. Is their a modern day equivalent that will perform the same as OEM?? webdawg1
