Fuel pressure test port location

Could someone tell me where the fuel pressure test port is. I believe it is on the passenger side but I must be over looking it. A picture would help alot if anyone has one. Also what should I be looking for at idle and WOT. Thanks

It is on the driverside slightly off center and it has a hole for an allan wrench. It is a #4 ORB. Factory specs are 51psi +/-4psi all the time.

Anything below 40psi and you are loosing performance.

Stokinearly is this where you would mount a pressure gauge? Also do you know what and how many fittings that I would need to get it spaced up and ot of the way. Im looking at a gauge with a 1/4" npt connection.

You will need a 90 degree 1/4" o-ring fitting with a 1/8" pipe thread on the side that goes up for the fuel sender. At least thats what I used. Hope it helps. And they are located in the back of the fuel filter housing.

Yes, this is where you can put on a gauge or sending unit. You just need to get the gauge far enough away from the bowl to fit the gauge in there. Maybe a long L #4 JIC.

Look here for fitting ideas:

SAE 37° Flare (JIC) Hydraulic Tube Fittings

Straight Thread O-Ring Hydraulic Fittings



I do not like the idea of drilling a hole in the fuel filter cap or clamping a hose on the drain valve. I have done them both and the hose on the drain valve kept popping off and flooding the valley with fuel. And the cap gauge vibrated loose when I drove it.

It is a #4 ORB(O ring boss), it is also called a 1/4" ORB. Depends on who you talk to and what shop you go into. Parker employees live buy numbers and acronyms.
