I can\'t tell how much gas my truck has

Sometimes my tahoe says I have 1/4 tank, then next thing I know it says I have 3/4 tank.
Now you probably think, hey, moron, you probably put gas in it. But that is just not the case. The guage is all over the place randomly. So what is the fix for that...do I have to take the gas tank off...please god no!

Could be wire from sender shorting out or could be a bad sender. To replace the sender you have to drop the tank and the unit costs about $300 [img]images/graemlins/shocked.gif[/img]

A lot of places if they have to get to the tank they will loosen the bolts one side of the bed and take them off on the other side. They will tilt the bed and put a 2x4 in there to hold it up. The stealerships do this, BUT I am sure they still charge you the same.

Laters, Ryan

Re: I can\'t tell how much gas my truck has

I dont have my partsimager in front of me right now, so no pictures this time... You simply need to go to the dealer and specifically request the fuel pump module level sensor. Its a float sensor that simply snaps onto the side of the fuel pump module and that will fix your problem. Its a common problem. Its a dealer only item so dont even ask for it at the Zone... they will look at you like you are crazy for asking.

On a side note... I know you may not like the sounds of it, but your module is a few years old now (assuming this is the 99 Tahoe you are asking about). The pump modules they used in these trucks are almost guaranteed to fail within the first five years of the vehicles life. So if you have the money to do it, and only want to do the job once, get the module and replace the whole thing. Trust me on this one, I work for a Delco warehouse, and there is nothing there I sell more of in a week than the GM fuel pump modules out of C & K trucks and Silverado's. Just a small piece of my mind. Good luck to you either way!

Well this is a downer. I just bought the tahoe from a used dealer about 2 weeks ago. "As is" is always fun!
Is this a hard replacement to do? Unfortunately where is moved has made for limited work space. Oh well...thanks for the input.

nope, not hard to do. actually quite easy. only hard part is that the gas tank is big and heavy when full.
