Fuel pressure/test port
Hi, does anyone know right off hand, on a 2004 6.0 what is the type and size adapter needed to use in the test port on the engine mounted secondary fuel filter housing, to attach a fuel pressure gauge sending unit? I'd like to go ahead and buy the parts, so I can just take it apart and do it all at once, and not have to find a ride to run me all over town looking for parts. I have the blue spring regulator upgrade, but I'm getting a code that says Injector Control Pressure Low (or something worded along those lines) so I need to check it at all throttle levels.

Other stuff coming soon, including tunes from Matt @ Gearhead's, STUDS, full EGR delete, real exhaust, and bypass oil AND coolant filtration.
