Fuel pressure test port

[Mikesf250]

Fuel pressure test port. What size fitting and thread size is this port on a 7.3L? They only make fuel pressure kits for my Qzilla Commander for the 6.0. But Qzilla tells me that all I need is a larger fitting for the fuel pressure test port connection and it will work fine So I need to know what size fitting to put in there. I could use my Tap kit to find out but thought someone may know off the top of there head.

Thanks Mike

1/4" NPT, I think.

Its an AN-4 fitting. IT IS NOT NPT!!!

[Mikesf250]

So just ask for AN-4 fitting?

[CSIPSD]

yup... Or just drive your truck to the store and pull the fitting out there. But its a An-4 fitting...

[Mikesf250]

So it is an AN-4 to 1/4 inch flare.

[CSIPSD]
