Time to replace the fuel pump

I have a 2001 Silverado with a 5.3L showing some sings of a failing fuel pump, specifically it's hard to start and the fuel gauge jumps all over the place. I know there are two different main types, with and without evap emissions. How can you tell which one your truck needs?

Thanks,

Kris

Look under your truck in front of the gas tank. If there is a rectangular black box with fuel lines running into and out of it, that is the evap system. If you have the evap system, you need the evap compatible pump.

I checked and sure enough I have the evap box in front of the fuel tank. Thanks for the help.

I would also take a look at the fuel pressure regulator. I wouldn't be surprised if it needs to be replaced as well.

No problem. Good luck with the install, and don't forget to replace your fuel filter while you're at it.
