fuel pressure gauge install problem

[selmerguy]

i have a electric autometer fp gauge and i can't find the adapter to go from female -4an to 1/8npt. can someone give me a link or a idea on how to install this on a stock fuel rail. i plan to install my sfmu in a few months and i know i can get a adapter from female -4an to male -6an with no problem, but i would like to see what my fp is like now with my current setup. thanks

I don't know if they make a direct reducer. I had the same set up for my feed line, 1/8 screw into turbo, but 1/4 for the line, I had to get a 1/8 nipple, then a female 1/8 to female 1/4 adapter then the 1/4 flare 1/4 standard hex nipple to go on top..I'm not sure if fuel fittings are flared or not, if not of course just a standard 1/4 nipple will help. I've taken the time to give you this cute little drawing from paint...To help better understand..Though you probably already did and I wasted my time Anyways, goodluck

got it installed today. i had napa make me a short piece of hydraulic line with a 4an female on one end and a npt fitting on the other. works great. what should my fp be on stock injectors at idle? mine seems to hang around 60 or 50. is this normal?
