    What is the best way to replace the fuel sending unit on the fuel pump in the gas tank. (2000 silverado 5.3L) Drop the gas tank, or take the bed off? Thanks

    I love these forums!!!

    I second. Take as much fuel out as you can and it will make things a LOT simpler for you.

    Dropped the tank, unless you want the enjoyment of removing the bed.......:rofl:

    Drop the tank unless you have a couple of big friends to pick the bed up and slide back a foot or two. Anyway you can't just replace individual parts on the fuel pump. The fuel pump and fuel gauge come as an assembly. Kind of expensive.

    I've actually heard that taking off the bed can be easier. I can imagine it being easier once you get the bed off, but I'm sure it's no easy task removing the bed. Might be easier if you have a couple friends to help, like k.daddy said.

    get it onto a lift if you can pulliing a tank w a vehicle on jacks is a PITA.

    I have done it both ways and removing the bed is by far easier. Only 8 bolts hold the bed on and there are a couple of wiring connections to unplug. You (and a couple of friends) can lift the bed, move it back so the part in front of the tire rests on top of the tire and the part behind the tire sits on the bumper. You will have plenty of room to disconnect the fittings and remove the pump. You can replace just the sending unit (about $100 at the dealer), I did it recently in my dad's 05 Yukon XL.
