I am wondering what thread the male flare fitting is right off the firewall going to the hose that connects to the fuel rail.

It seems to be a 1/4 NPT, because thats what fits into the female part, but a female 1/4 NPT does not fit into the male thread on the car. Is it a metric bastard thread?



I am hooking up a fuel pressure gauge, and would like to tap into that part, I am not going to cut the hose!

 

contact Rob at Forced fuel in Miami, Fl. He has a kit already made up for this line.

 

you happen to have a number for that shop?

or is this the correct site? http://www.force-efi.com/index.htm

 

cut the hose, it's no big deal. You need this adapter for like $10 in the first picture, the red one.

btw, the thread size is 14mm 1.5 pitch -

 

Thats correct.
