Got appt next week minor stuff in shop, just bfore make appt, I see fuel gauge at empty or almost when stop post office , left went back up 3/4, then at home it drop to half tank, then went back up close 3/4, never did that bfore, had new fuel pump 2 yrs ago, I rrmber a 2001 that was on empty on guage for yrs, a sensor on pump an not got fix, I spray fluid film on inside fender up by wires from tank by fuel tank lid door on backside bcause rusted, is possible could cause bad ground with oil on ground wires on body ? Anyone know aslong as gas in tank if pump keep pump no matter what guage say ?

Yes fuel pump pump gas no matter what gauge say will pump as long as there is gas to pump. your gas gauge could be going bad or maybe you were on a hill and the level didn't level out fast and needed time to settle back to get accurate reading.

Oh no! Fluid film done ate a hole in the gas tank!!!

No I spray it on back side fender , lot rust by wires that look like ground wires from fuel pump or at least close it an gas tank that ground out close backside tank lid door for gas cap , probly oil do nothing connection,I don't know, my 87 S 10 was park months bfore tow shop yrs ago an a bad ground for fuel pump I believe an wouldn't run,I rrmber the gas guage did same thing bfore quit, go up an down n fluctuate

Just think , if you didn't have to pay for the new street and broken water/sewer lines you could buy a New truck .

I just reasearch, probly broke float lever for fuel gauge or bad send unit for guage or ground wire if is for guage, of fuse, I don't card about guage, aslong as it goes, fuel pump was gm fuel pump replace 2 yrs ago, I was just thinking ground wire on old truck for pump an quit run an flucate guage, I doubt that happen on this truck , that quit run

Broken most strands of your ground wire are.
Fix it you should. Yyyyyyyyyees

Yeah what Yoda said.^^^^

Just carry 5 gallons of gas with you and watch your mileage so you know how far to go on a tank.

Classic. Turn it up louddddddddd..............

Nice song, Delaware Rob.

Don’t let the gas in the tank run real low as that what cools your fuel pump, it will burn up your pump if you let it stay low all the time.

Failed fuel gauges was a problem on a few Chevys I owned several years ago and had friends with same problem. I never wanted to spend the money to fix it so just reset the trip-ometer every time I filled up and knew I had to get gas by the time I hit 300 miles.

Ya the fuel is what cools them, he show me old an new fuel pump, pretty good size, new pump without labor was $400 for genuine gm replacement part , they rust out on top tank where go in at an was leak gas is why replace,

... you need to get you a old jap rice burnin vechile ... hate to say it but they’ll outlast the yank made vechiles ..and if you can’t find gas due to cyberattack pipelines and what have you... they’re known to get 25 miles per ounce on soy sauce

I run my vehicles on 1/4.or less 90% of the time. You won't burn a pump up unless you constantly run OUT of gas

This is correct, most common cause of fuel gauge issues is a broken or damaged ground. I always start by checking the ground on all vehicle electric problems

So a fluctuating fuel guage if broken ground wire could shut ur fuel pump down ? I fill up gas last nite an not done it since, it did it several times
