Fuel pressure problem???
My truck has a low pressure dummy light mounted on the injector pump. I'm not sure what pressure it is set to but started flickering every time I got on it. I replaced the lift with a fass platinum 95gph. It helped a little but am having same prob. When It first started I noticed my tank had vacuum on it when I remove the cap so I drilled a hole in it for now. Also I have a van aaken pump programmer. I'm driving a hour and a half one way to work six days a week and would appreciate any input befor I ruin my injector pump.

I am planning on buying a fuel pressure gauge to see exactly what I've got going but won't have it for a couple more weeks.

Do you think that could cause my pressure problem? Just pulled my truck into the garage to look into it. Thanks

Look at your diagram for supply and return lines from the fass pump you probly have the supply and return lines in the wrong locations. The truck will start and run on the fuel that is being returned from the fass pump if they are swapped and pressure will read around 3-5 psi. It will also pressurize the fuel tank
