Where is the fuel filter located on a 2002 GMC 1500 sierra

I have been told by a mechanic that the fuel filter is inside the fuel tank. Have to either drop the tank or remove the pickup bed. Access is on the top of the tank. This is poor engineering.

Drivers side on the frame rail.

It is probably the fuel pump. If I remember the number correctly, this fuel system needs about 50 lbs to open a valve.
Until this valve opens, no fuel gets to the fuel nozzels.

Really by the way you describe it you need to check the fuel pressure. There is a valve on the fuel rail for testing it. You will need a fuel pressure gauge. It should have 55 to 65 psi. It will not run on less than 50 psi. If you have less then it will be your pump. Good Luck
