My 318....Is no more..... :(

screw driver to the end of your ear works just as good....don't bother spending the money....a little late for that anyhow.

as for the 70 psi...I am assuming its a factory pump since it wasnt mentioned other wise.....and it sounded like it recently started pushing 70 psi....... or has it always ran at 70?

either way it sounds high.

normally at idle 25-40 psi is an average psi and at highway speed around 50 psi
