fuel pressure gauge

[melmount]

i have a mechanical new gauge and line. where do I hook it to on a 6.0?
used to have it on a dodge, no idea where to install it to?
thanks

There's a little test port plug on the engine mounted fuel filter/ regulator housing. It is metric o- ring thread (can't recall what size). Maybe someone has a picture...

I hope you are not running a direct fuel line into the cab, that is a big no no if you ever get a leak, you will at least have a mess. There are isolator fittings available for the job. Or do like alot of guys and get an electric fuel pressure gauge.

what size would be cool to know?
thanks

I second what RoyBoy said about running the fuel line into the cab.

Well since it was on a Dawdge it's useless on your PSD....it will be pegged all the time. The PSD has about 60ish psi at the test port, all the Dodge systems(VE, P-7100, VP44 and HPCR) run low pressure...5-13 depending on the situation.

really, their is that much pressure? This is before the injection pump of some kind? I also assume it gets a lot hgigher after the injection pump?
Ford have an injection pump??

Now you know why the Powerstroke has so much better power than the cummins

just kidding

It is the fuel pressure fed to the injectors. No, the Powerstroke doesn't really have an injection pump,HEUI (Hydraulic Electronic Unit Injection) each injector is its own pump and pressurizes the fuel and injects it. The injectors are powered by the HPOP (high pressure oil pump). Injection pressure is variable, up to 26,100 psi.

where is the test port on a 7.3l?

 

[melmount]

so in a nut shell, a 30 pound gauge is too low a reading??
I should sell it? get a 100 psi??
let me know this, i have a guy who will take it. fittings and all he has a dodge 2007.

In a nut shell.. Yes, to low.

May as well.

A 100 psi guage would work. 70(ish) psi is where a 7.3 likes, or should be. Stock is 50(ish). Shim yer FPR to 70(ish) and yer SD will idle quieter and run better.

Theres a DYI or WIKI on how to do it.
