Anybody know the thread size on schraeder valve???

[noslow5_0]

ok, trying to use a fuel pressure gauge that a friend gave me. It has 1/8"threads coming out of it. I have gone to every hardware store, plumbing store and auto parts store trying to find an adapter from 1/8" to what ever thread the schraeder valve is... Anybody know????

In hose size terms...its -3an line..if that makes sense.
May be metric. Not sure. I have a line coming of mine to a gauge and its a -3.

Could be 3/16..thats what the summit site has listed

1/16th i believe. I searched everywhere also...came up with nothing local. Ended up ordering from Jegs. Its called a ford fuel rail adapter...go figure.

I did this a few years ago and wasn't able to find an adapter. What I ended up doing is getting a 1/16 female NPT nut to 1/8" tube fitting, installed a short piece of tubing (1-2 inches long) and had a 1/8
tube to 1/8" NPT nut on the other side.

This has worked well for me for about 4 years now.

Good luck. You can unscrew the scrader valve and test your newly purchase fitting before you do all the work.

1/16" NPT - only place I found them was a Summit, Jegs, etc. I bought mine from Earl's at WFC last year.
