Engine/Transmission (1998.5 - 2002) Fuel Pressure Gauge Reading 4psi Low

[SConklin]

I have a 2002 ETH Ram w/ DDIIIs, a Drag Comp, and Wildcat Drilled Banjos. The fuel pressure gauge reads about 4psi low (I mean indication-wise, not because of the bombs sapping pressure).



Would this be caused by air in the line, or something else?



What else could it be?



Thanks,

Could it be you have low psi? or that the gauge needs to be checked out against a known correct gauge ? If you do not have a gauge to check against and have a air compressor you could set the psi at mid range of fuel gauge then pressure test the gauge it should show mid range reading . You can use the fuel gauge on air or fuel . Hope this helps . LOL Ron Bissett in Metro Louisville KY:-{}
