I had it done at a shop that does this sort of thing. Also the exhaust is a bit rusty and may have a whole or maybe a blockage, I smell it when I'm in drivers seat with door open. Could this have something to do with my problem ?

thank you ,- i'm kinda concerned it may be the tank, but can't find one anywhere, I didn't want to boil this one again, i think it may have varnish from the gas while sitting, although when i looked thru the tank, looks good i see the liner inside is clean, but maybe i missed something. so i guess i'll drop the tank and see, then post my findings. I appreciate the help guys

thanks for the info, i did get the manual and will look into it.

I posted this in fuel forum but didn't get any response, and i have to get my z on the road. My 1977 280z 4sp sat for a long, long time. Had a fuel problem years ago, removed the tank had it boiled and relined but still never ran. At present I bought 2 new fuel pumps, and finding out the universal pump I got was to weak(wasted $150) bought the proper one then discovered the tank outflow line is plugged) So I put a connector on the tank drain plug and am drawing gas from there, it drove fine for 6 to 10 miles, but consistently has got worst, now I goes less then a mile and starts acting up. The new pumps giving me 36 lbs past fuel filter where I installed a fuel pressure gauge and ran it so I could view the pressure and monitor it constantly. The car starts fine and drives for 10 -12 minutes then as I'm driving it stalls but doesn't die, kinda like its out of gear, pressure remains good, I clutch it and rev it, pressure seams to sputter a bit if I keep revving. I then turn car off for a moment and it starts right up and drives again. I'm sure I need to give more info but am at a loss at this point. It also back fires on occasion from the AFM I think. I gotta get this car outta here, Its a divorce thing, car or wife, I chose car, besides I had it longer then I had her. thanks for any help

Hi new to the forum, I have a 77 280z 4sp sat for 15 years, worked on it every few years because of fuel problem. getting divorced and need the car, had choice keep wife or car chose my z. Initially removed tank had it boiled and lined car still didn't run. Now I have discovered fuel tank is blocked internally, so I installed a new outflow line threw drain plug of tank, blocked existing outflow line. Installed new fuel pump,, changed plugs filter, car started right up and ran rough but ran. Problem is now that after driving a couple miles the car hesitates, backfires some when driving and then doesn't go, and drops to idle, i step on gas idles goes up abit then down to idle. I then turn car off, and restart it a couple minutes later and its fine again for a little bit, replaced pump and get 36 lbspressure, fuel seems to travel throughout lines, I am getting spark,Can it be something electrical, or module, relays? when opening the door on AFM the pump starts. I'm sure more info is needed to diagnose. I've been searching the forums but haven't located answer yet and I have to move the car. Thanks Aleck
