Pulling the fuel pump help please
I have a running issue with my truck, most likely the fuel pump. I have a spare for it, I was wondering if it was easier to drop the fuel tank or pull off the box to get at it?
Also, is there an in tank fuel filter that i would need to replace?

EDIT: Forgot to mention; you'll want a pump bracket gasket and probably a new set of bracket screws which you can get from the dealer. Your current screws are probably completely rusted.

OK sounds good. I have a suspician that the pump itself is ok, but that the sock is almost completely clogged up. When i beat my truck up a bit my driving over speed bumps fast and over curbs and other bumps it often works better for a short period of time

Could also be corrosion. But while you're in there, may as well replace the pump. If it's original it has certainly give a lot of years of good service. Probably earned its retirement, lol.

Before you bother with any of that, jump +B and FP in the diagnostic block. Use heavy gauge wire. If the truck runs, and drives well the fuel pump isn't likely to be the problem.
Jumping those terminals will feed the pump 12v, bypassing the COR.
