New member with a problem (long)

[Gunner Jake]

Hi guys I've been lurking around here for a couple of months and decided it was time to become a member, and I hope you guys can help me out. I've been building and racing cars all my life but my 85 GN is my first turbo car and I can tell you it's like nothing I've ever driven. Well anyway on to the question my GN has developed this nasty habit of smoking and loosing power whenever I get to the last 1/4 of a tank, If I refill it (with 93) and park it for 30 or 40 minutes it clears up and the power comes back. I really want this motor to last me over the winter while i build the new one. ( Fresh 3.8 block, 86-87 coil adapter,bowling green down pipe, 110cc heads from Ron's Performance, Garrett 48*65 turbo, Hotchkins Intercooler , 7th injector and other goodies) anybody got suggestion? I'm hoping it's something like a bad fuel filter which would explain the loss of power but not the smoking. Any help from you guys would be greatly appreciated thanx

Welcome!

Sounds like maybe your running to low on gas. The gauges aren't
real accurate. With the in-tank pump the gas actually keeps the
pump from overheating. Might just be a matter of fueling a little
sooner.

I would change the filter and keep at least a 1/4 tank in. Mine runs out of gas when the gauge reads between 1/4 - 1/8 full.

My gauge NEVER gets too low. I'd say it bottoms out at no less than 1/10th or so. My low fuel light has never come on, and I've drained the tank completely (when I changed my pump).
