Question about a fuel pump...


Recommended Posts

On my 2002 Z71 the fuel pump went out and I had a new one put in. Now the pump is really loud...

I was thinking maybe if I change the Fuel Filter it would cure it...

Nope...

It's still loud...

Any ideas on what a guy can do...

Thanks...

I worked in a gm dealership parts department for 5 years. we would give people the choice of aftermarket pump also because of the price difference. they were all louder. i do recall one instance though 3 gm pumps were put in the same vehicle before it was quiet again.

Yep that's pretty common

Yep. My 98 has the factory pump still and it whines a bit. We got a round of bad gas somewhere and had problems with fuel filters in both the truck and our gmc yukon, they whined a lot worse and acted up, changed the fuel filters in both and the problems went away and whine got better on my truck, but still can hear it. Try to change the fuel filters occasionally(15-20,000 miles), less restriction, less additional work on the pump. Think fram suggests changing them every 10,000.
