Installing A Fuel Pressure Gauge - What Size Is The Fuel Rail "Test Port" Fitting?
I want to install an electronic fuel pressure sensor/sending unit onto the fuel rail "test port" at the back of my stock LT1 fuel rail.
First question, what size and type is that male fitting on the rail? It looks like it might be something like a -4AN fitting, but .... I'm not totally sure.
Second question, where can I find an adapter, maybe something like a female 1/8"-27 NPT, (needed on the sensor/sending unit side) to a female -4AN (???) on the male test port side???
TIA for any replies.
