Fuel Pump Replacement

My fuel pump seems to working intermittently. I had it tested at Chevrolet and was told the check valve was malfunctioning, letting the fuel drain back into the tank, and the pump should be replaced. The pump was creating good pressure (a little lower than ideal), but I have had problems with the engine dying after it is started.

How difficult is it to replace the fuel pump? I know I have to drop the fuel tank but I could only locate two bolts holding it up with a bracket-type mount on the other side of the straps.

Is there enough play in the fuel lines for me to drop the tank to the ground without breaking anything?

Do I need a new wiring harness also?

I believe there are two bolts on one end and the other end is hinged. The hoses are not long enough, nor is the fuel fill line or wiring harness, and surely if you just let the tank drop you could cause serious damage to yourself and the tank.

You have to block it up and slowly let it down until you can disconnect all lines and then you can precede with dropping the tank.

You do not need a new wiring harness.

I have a 2002 Silverado step side bed I replace the fuel pump with my eight year old son. I found out it would be best to remove the bed. A friend recommended I do it that way and it was the best way from my opinion. Only eight bolts hold the bed to the frame and remove the tailgate before anything its in the way of the wiring harness the lights are all plugs. Disconnect the fill tube from the the fuel door three screws and let it hang. Tilt the bed to the side and hold it up with a pipe I used the broom stick (not very safe but worked) or completely remove and set it on buckets or blocks high enough the bed do not sit on its ends. All you would have to do left is remove the fuel pump.
