Low Fuel Pressure

i have a 1995 e350 diesel 7.3L box truck. we have had it computer tested and the only thing that comes up is that it has low fuel pressure...it runs as though it is missing and won't pull itself. does anyone have any idea as to what could be wrong with it?

can the value inside the tank concerning the fuel gauge be bad and causing it to have bad pressure

Normally low pressure is attributed to one or a combo of these
Low tank level
Fouled lines
Stuck tank transfer valve
worn out fuel pump
dirty filter
dirty mesh filter at fpr
dirty fpr
dirty vent screen
particulates in the bottom of the fuel bowl
Tank delamination
Algae/Microbial growth in the tanks and lines

Im sure there are a few more someone may want to toss in here too.

Try filling the fuel bowl with diesel and when it cranks give it throttle til the air gets ot of the line. Get it on the road then and run it.
