that switch is proble for a gauge,
it depends on what year and model if it is hooked to the fuel system.i think you can bypass all that if you no how.
I have a electric dash gauge [stock] . them sender units may operate at different psi I don't no.
it depends on what oil I use ,my 4.3 has 20-35 psi at idle .
