Alternate method for fuel pump change in chevy truck?

Hi, I have a 1990, Chevy, C15,Pickup, w/4.3 L motor,w/a 6ft bed. I need to change the sending unit,%26amp; while I'm in there, change the fuel pump as well,(milage:150K).

My Question is: I've heard that to%26quot; Avoid dropping%26quot; the tank,which has approx.150 lbs. of gas in it,(20gals)@ present, a person could simply raise the bed.

I have a floor jack. I also have a bed liner,which would be difficult to remove, due to the tie-down hardware.

Has anybody accomplished this before? If so,how?

Can the bed bolts be accessed underneath,without removing the bed liner? Thanks,in Advance! Everybody!Alternate method for fuel pump change in chevy truck?Six to eight bolts hold the bed on. Disconnect the wiring harness at the rear of the truck, get a couple/three friends to help and lift the bed and move it back about three feet. Fuel pump and sending unit will be visible right behind the cab. Use a brass drift punch or piece of wood to remove the retaining ring and remove the wires from the unit and lift it out.



Just did this on my '96 C1500, 4.3l and a short bed, same as yours about 2 months ago, not a bad job at all. You do not have to remove the bed liner, all the bolts are visible from under the truck. I had to take the rear bumper mount bolts out of the frame to gain access to the back bolts, but the rest were easy, I think it was a 14mm socket. Also will have to remove the screws holding the fuel filler neck to the bed. Had two buddies helping and it only took me about an hour.Alternate method for fuel pump change in chevy truck?Raising the bed would be 2X the work compared to draining the tank and lower it with the jack.Alternate method for fuel pump change in chevy truck?Doing it this will add about 6 hours to the job plus you might have alot of electrical issues after the bed is back on.



Dropping the tank after you have removed alot of the gas is a piece of cake and alot easier....
