Normal Fuel Pressure for Returnless System
I have a 99 Ford Explorer Sport 4.0L V6 SOHC and was wondering if anyone knows what the normal range for the fuel pressure should be.
I have a Chilton manual that says it should be between 35-45psi but when I hooked up a fuel pressure guage, it read a constant 65psi. I have a feeling my manual could be wrong since the chilton manual shows a return fuel line system and I am positive that mine is a returnless system. I just can't find anyone who knows what the normal fuel pressure should be in the returnless system.
Any help would be greatly appreciated.
Thanks,
