Buy a clear inline filter with replaceable inserts and see the fuel pumping.

Probably the best way is to use a line pressure gauge on the discharge side of the pump while the engine is running. NAPA sells a decent gauge that is a pressure/Vacuum gauge that works well.

A new fuel pump is about 15 bucks. How much trouble is it worth to you to just put a new one on?

Tx Firefighter, thats a good point, but I would rather check it so if it is ok I can spend the $15 else where as the truck does need alot.
How much pressure is the fuel pump is suppose to put out?
