Can the shrader valve adapter with the 1/16 female onto a 1/8 male be bought at a hardware store. And can I then get a 1/8 90 degree elbow for a fuel pressure gauge also a common piece. The adapter is fifteen bucks at LMR........do I have to take the pin out of the valve..Noobie with this.
Do you have a part number for this valve? I have a gauge hooked up, but no valve and Ford in my old hometown forgot how to look up parts this old.
With the 1/8 NPT male fitting the whole shrader valve threads out and then thread the fitting in its place.
This is what you will remove.
Here is how I have mine installed. Basically removed shrader valve, installed adapter fitting and then attached gauge.
Cj pony parts and LMR have valve assemblies new for less than $12. They are probably making a good amount of mark up, but the local pull a part is full of dead Dodge mini vans and not many Mustangs.
And it’s too hot to hang out at Walmart’s parking lot for one.

Can you see it good strait up the way you have it. From the side of coarse. This is one of the only how to thread on putting on a fuel gauge here

I made my own pressure gauge and holder. I bought the NOS or Autometer adapter that you screw into the place on the fuel line where the Schrader valve goes. You have to remove the Schrader valve, but save it, since you will reuse it. I ran a piece of SS (stainless steel) braided hose to a 1/8” pipe brass tee fitting that I mounted on the fender well by the MAF. I made a mount bracket out of aluminum angle I got from Home depot and bolted it to the fender well. Then I mounted the brass tee to it with some machine screws and a plate. I sandwiched the brass tee between the aluminum angle and a flat piece of aluminum that I trimmed off the extra aluminum angle. Three screws laid out in a triangle pattern go through both pieces of aluminum to clamp the tee in place. Put the Schrader valve in the spare port of the brass tee. I used a cheap industrial gauge from MSC Direct (http://www1.mscdirect.com/ P/N 56468499). It works great and was cheaper than (less than $8) anything Summit had.
If you look through the MSC Direct catalog, you can find any type of gauge you want, including liquid filled. You only need a liquid filled gauge if you mount it directly on the engine. The liquid filling dampens out the vibrations. .However there are a couple of people who have had nasty engine fires when the gauge or the fuel injector rail broke due to vibration because of the gauge directly mounted on the fuel injector rail.
You can buy the Autometer Stainless Steel braided hose for like $60. Or a local shop that makes hydraulic hose assemblies can make it for you at a cheaper price. Ordinary low pressure hydraulic hose can be used in place of the Stainless Steel braided hose, the Stainless Steel braided hose just looks nice. I got mine for $4 at a place that sells industrial and military surplus parts of all kinds. The Stainless Steel braided hose goes for about $4+ a foot and the fittings are probably about $6-$10 each. You can make your own and save some $$$, the shops may have a setup or labor charge to fabricate the hose assembly.
