gas gauge/fuel pump not working correctly?

[drowndindreams]

The fuel gauge up front hasn't been reading correctly. My father states that it's the fuel pump, which is about a $900 fix.

Any suggestions? Or ideas?

900 bucks is a little steep. Why isnt it reading it correctly? is the needle bouncing? or does it say full when your out of gas? more info..

 

[drowndindreams]

Well I've been noticing that I was filling up constantly,

and the other day I measured it, I filled up $20, and it went up to a quarter tank,
and by 35 miles she was already on E

the fuel pump wouldnt have anything to do with inaccurate readings. I believe it would be the sending unit. Do you have a leak? do you notice the fuel pump whine getting louder??

Try using a different gas, preferably a Top Tier manufacturer. toptiergas.com

In the mean time try putting a bottle of Techtron in the tank.

Atomic : Yes it is possible the whiner is growing louder, but I'm not too sure of it. I haven't noticed any leak, and what would the sending unit cost me?

Snowjay : Techtron = ?

At your local auto parts store.

 

[drowndindreams]

Atomic, yeah, I'll do it myself, thanks for the offer though,

Snowjay, I didn't realize you were talking about fuel injector cleaning. Have it done about every 3 months.

Not just any cleaner Techron which is the same as the GM cleaner mentioned in the TSB I posted.
