#101235, "Fuel Pressure Gauge Fitting"


          

Hi, im about to hook my Electrical fuel pressure gauge but it has a 1/8 Male NPT. I know I will place it on the fuel rail test port but I have to remove the valve and after what fitting do I need to buy ?

is it a 1/4 npt male to 1/8 npt female ?

thanks!

Some aftermarket applications use the fuel rail test port as a place to hook up a bleed line that returns excess fuel to the tank (thus controlling fuel pressure).

You can just cap off the top port and it would then be available in the future as a standard test port while your electrical gauge can remain hooked to the side fitting.

Or, if your not running a return line that the above mentioned fitting would be used for you can run on of these:


-4 AN female to 1/4 NPT female

hook the -4 AN side to the test port with the valve out and the electric sender into the 1/4 NPT...pretty straight forward...

I want to use the test port (the one with a valve). Ive removed the valve and the tread is male. Ill need 1/4 Female to 1/8 female since my gauge is 1/8 male.

Its not 1/4! Thats what people are trying to tell you... It is an AN fitting. Read the above link to learn about the differences.
