Put a fuel filter in it and now I have gas in the rail at least, but very little pressure.

The freaking bed has a bedliner with 8 1/2" shank eye hooks bolted thru it into the bottom of the bed with 8 rusty nasty looking nuts under the bed. This changes my plan of attack on the fuel pump Im affraid...

Is there only one pump on this thing in the tank? Im getting conflicting info, and I dont see another one anywhere on the frame rails.
