Low fuel pressure
Hi Guys,
My '97 F150 (5.4, 4x4) has a fuel pressure problem.
The truck shows 30-32# pounds of pressure at the filter, but only about 20# at the engine.
Any ideas on what would cause such a drop? I've replaced the pump and filter. The symptoms haven't changed a bit.
Thanks!!!

Check for any restriction between the filter and the rail.
Check the pressure regulator and pulse dampener.
