fuel rail test port

[baxsom]

does anyone know the size of the fittings for the fuel rail test port
i want to upgrade my fuel lines to steel and use the Earls fittings but i am unsure which one to get for that part

thanks

a -4AN fitting will fit

awesome thanks
does this mean that i need a 6an to 4 an reducer since the fpr is a 6 and the hose from the rail is a 4
or can i use a 4an fitting on the rail size and a 6an fitting on the fpr side with the same hose

is this the correct fitting to come off of the test port and do a 90 degree turn

That would work AS LONG AS, the red hose connection is a -6AN. From the looks of that pic, it appears to be -4AN. Something like that with the -6AN hose fitting will suit you fine.

What they both said ^^^^^^

i just ran the line right off the test port without a 90* turn. still works.

that is a 4an hose fitting
the test port is a 4an

i need a 6 to 4an reducer to go into the aeromotive

i already have a 4an barb coming out of the test port
so i can get another one to screw into the 6-4 reducer and still use the same hose
the return line is a 4an also so another barb and i can add the aermotive without having to break the bank replacing all of my lines just yet

i am still iffy on a new fuel rail
i would like one that is 6an in and out
but i have just read too many bad things about venom and obx
i guess i could drill and tap my stock one
but how hard is that
