If your truck is having a mechanical or electric pump? You need to replace the filter. If the pump is electrical then it will be bit expensive (compare to mechanical)
When the original pump went out on my Scrum I replaced it with an Auto Zone in line pump and started dumping fuel into the crankcase.I replaced it with the after market pump that G&R is now selling for$125 but only have about 100 km on it so not sure yet if this cured my problem but this new pump causes a lot of static in the radio. If you go to a generic pump be careful to not overload the return side of the carb.

The fuel pump itself is located up by your gas tank on the drivers (Right) side rear frame rail. its easy to see, should have two fuel filters close to it.
