i want to put a pressure gauge on the schrader vavle on my car so i can adjust the fuel pressure.

does anyone know the thread that is on the schrader valve?

i have a 97 ta if that makes any difference

thanks in advance

 

the thread size is 04an. my suggestion is to get a swivle fitting that is male 04 to female 04 then run a braided line about 18"-24" and mount what ever you want on that. also don't tighten the swivle fitting to much cause you don't want to pop the pressesd metal line out of the fuel rail. summit has that fitting for i think $9.00.
