im no admin or no one of authority but please no thread hijacking.. let the person who started the thread get his help... thanks.. its annoying to read 5 peoples questions in one single post..

i dont even know if anybody is still watching this thread anymore but my sending unit had a leak in it and my gas tank had a small hole in it so i had it replaced.but after everything was connected, the new unit was jumping all over the place. what should i do? fill the tank up completely and then it should ork normally? of it'll correct itslef eventually?

I donno 'bout you Pontiac guys, but I scored a OEM fuel sender on Ebay for 79.00 for my '95 88. Similar problem 'cept it seemed be stuck on 3/4 full. I figured there was an issue when I was pushin 250 miles on a tank and it still was on 3/4. I figure in another 80 miles, I can drop the tank without the help of a jack. :o
The part I got was ONLY the sender unit so I will hafta transfer my old fuel pump. Having a working fuel gauge is a big issue with me since this rig is my "road" car. IF this thing works, I will report back the results with the part number and manufacturer of the "sender only". I to was choked when I saw 300+ for the "fuel module. I figure the fuel tank in the Bonnies can't be much different form a lead sled 88.

also too i wanted to throw this in here real quick. when the gas is about 1/4 tank w\hen you come to a stop is the car supposed to stutter and shut off at times?

Has anyone had success with Advance Auto Parts Fuel Sending Unit for $57.48? Seems like it would be missing something for that price, but the picture shows a complete Sending Unit

P.*. Same part number at Auto Zone $174.99???

Just so you know, you're on the completely wrong path. Your problem is your tank baffles are defective. If your gauge reads anything, and your car runs with no problem, and your fuel pressure is good, then you have no problem with your sending unit OR pump, you need to replace the TANK. now if you want, while you're under there, its not a BAD idea to replace all three since you have it apart, definitely will save you alot of time from having to do it, or have it done again.

Older OEM tanks are either not baffled correctly (1992 usually) or have broken baffles. Cheap quality aftermarket tanks can be worse.

This isn't a pump or sender problem at all, and never was. WJcollier is right on the money. This is a tank baffle issue.

so what would be the solution to it since he was just stating that aftermarket ones are worst? because i already replaced the tank when i replaced the unit. i got both from the JYor should i just try nad find a tank from a newer year? it should fit right?

Get a tank from a 94/95. Swap your pump and sender into it.

Make sure the baffling is intact when you do it. Make sure the baffles are no worse than this:

This one causes me no problems except at the dragstrip when I'm on fumes and under hard accelleration. I have to maintain about 1/4 tank to keep things fed right at the track (lean under boost is a very bad thing......very very very bad)

correct me if im wrong but your saying that the section right under the hole where the unit enters and ggoing toward the front of the tank in the middle is the baffle?
