need help replacing fule pump on 1999 chevy 3500k crew cab

Drop the tank to the ground,and pull out the old pump.Your 3/4's of the way there. Are you sure it`s the pump?

Remove fuel lines. You need to get the tool which is available from Autozone to undo fuel line clamps. Once you remove fuel lines, you can lower the tank to the ground provided you removed the gas filler hose and grounding strap from the truck bed. Once on the ground you can remove fuel pump and replace. Reinstall by reversing the order of removal. May want to change your fuel filter while you are at it.

It may have been easier to lift the bed then to drop the tank, especially if the tank is full when it went out.

yep, it was the pump....got it....thanks, it would have probally been easier to take off the bed and just lift it out, but got it out and going to put new 1 in tomorrow, and filter..thanks again for the help, your more than welcome to come and put the new 1 in tomorrow......what a pain.. 8O

no thanks... been there done that on our 89 2500 , 92 K1500, 89 K1500, 95 Blazer, 95 Jimmy, and everyone needed a sender unit because the tubes where they meet the fuel lines were rusted off. Both K1500's also needed the entire fuel lines up to the front. They all went at around 170,000 miles Good luck...

Why some of the Chevies and GMC's fuel lines have those flare nut/power steering style fitting that are guaranteed to rust solid, which necessitates both a hacksaw and a new sending unit when replacing a fuel pump is beyond stupidity

Maybe you can cut the fuel line a ways back from the sending unit. Then get a compression type coupling. I of course have no idea if this would work or not.

What does this have to do with the guy getting his pump out?

HMMMMM did I miss something?

Also, when putting the new pump/sending unit in the gas tank, roll the rubber gasket up onto the pump housing, and then push the entire unit into the hole. Don't set the gasket in its seat and then try to push the pump into the gasket.

Hmmm just a bit....The coupling nuts on the lines to the sending unit were rusted tight....turning them only succeeded in twisting the metal lines beyond usability..

A Snap-On magic wand was of little use, so the hacksaw was a better choice than a plasma torch

Next time you run into this, there is a little trick that I do to both remove the lines and save the sending unit. Instead of trying to turn the nut (which is rusted to the metal line on the sending unit), you turn the rubber hose end until you have unscrewed it from the nut. This will distort the rubber hose a bit, but hey, it's rubber it will spring back. Once you get the lines off, drop the tank, remove the sending unit, remove anything that might melt, and heat up the rusted nuts and lines with a torch. If you are careful, you can get them loose and clean up the lines and nuts so that you can re-use them again.
