Permanent Fuel Rail Pressure Gauge

[Comanche91]

Here's a simple little mod I modified from TallPeter's post on the Yahoo Stroker group pages. This saves you time by enabling you to check your fuel pressure any time you want. The parts:
1.) A 0-60 PSI liquid-filled 1-1/2" fuel pressure gauge from Jegs, p/n 555-41012
2.) A brass 1/4" flare x 1/8" female NPT straight adapter fitting

Use teflon tape on the gauge pipe threads then snug it on the adapter:


After the engine has been sitting overnight and is cold, let any fuel rail pressure off first by depressing the needle. Have a rag handy in case the fuel squirts out. Then remove the core needle from the fuel rail Schrader valve w. an extractor tool, same tool used for bicycle tires.


My ever-present red-eyed helper:


Screw the assembled gauge and adapter on the Schrader valve. Since it's a flare, do not use teflon tape, and do not over-tighten:


Start 'er up and check for leaks. Hmmm, I'm about two PSI low:

My neighbor has a Cairn terrier John. She and my Gus are real good buddies.

How does that differ from Peter's? I'm pretty sure it was his that I saw in a pic. about a year ago. Seems about the same as what I remember his to be.
Since you showed your helper, I thought I'd show mine. I screw up enough I need 3.


This brings this thread dangerously close to being in the wrong sub forum and getting moved.

Different fittings, different gauge, but Peter's idea. Hey - I gave the Peter-man credit!

Beautiful Labs oletshot. They look so close. Did you just cut and paste two from the first and color their collars differently?

You did. I didn't notice the difference, and am to lazy to look it up. I felt it easier to ask you what you what was different.

Thanks about the labs. They are 3 brothers. Guess who didn't sell all their puppies.

Would it be a dumb idea to just have a gauge permanently mounted to the Schrader valve?

[oletshot]

It becomes a very bad idea when the gauge leaks or gets knocked off. Other than that, I see no problems with it.

Not just for Strokers, so i moved it.

Sorry to drag up an old post, but i cant seem to find "A brass 1/4" flare x 1/8" female NPT straight adapter fitting" on summitracing or jegs or anywhere else for that matter. Can someone point me in the right direction?

In case anyone needs this in the future, Comanche91 emailed me back about the fitting. It can be found here http://www.casperselectronics.com/store ... ts_id=1337
