Hi guys...
It's been a while since i've been on! I want to install a fuel pressure gauge and did some searching around (unfortunately the search function on here isn't working for some reason) and have figured that i can attach my fuel pressure gauge line to the shrader valve on the rail. I decore the valve and connect the fitting, attach the line, run it to the cowl, and attach that to the gauge.
Is that how you would do it? If so, what size fitting do i need to attach the line which is a -4 an to the shrader valve? i read somewhere that i need a female 1/16 in. npt to male -4 an fitting. is this correct?
i looked for one on summitracing.com and can't really find any. I found some that at 1/8 in. npt to -4 an, but no 1/16 in.

Thanks!

no it is 1/16" to 1/8" but you need 2 steps. i have never seen it it as 1 single fitting. so you need a 1/16nptmaleX 1/8npt female, then the an is -4 X 1/8npt male

#16785nos is the part number from nos for that brass piece

use paste not tape or it will clog the guage , and if you run a brass tee, you can split that rail into more ports incase you need another port later like for fuel pressure safety switch or fuel feed for nitrous

I bought a BBK Adjustable Regulator.....it has a fitting in the side just for the gauge.......

Do you have an adjustable Regulator? You know once you run that gauge....you are going to want the flexibility to tune your fuel pressure...

same here i have a aeromotive fuel pressure regulator and it has a port for a 1/8 port for a guage or?

i don't have an adjustable fpr yet... but i want to get one. for now i just want to check to make sure my fuel pump is giving enough pressure.

thanks for the help!
