in my pump someone had cut the bypass spring, it had only 50 psi or so at 9000, the pump came on my Nickens motor , I didn t feel comfortable with that so now i m running 70 -75



i was thinking on the same line when I put a new spring in it. The only thing I have not changed is the bypass plate it self. I guess thats next.



It sounds like the by-pass isnt closing all the way
and has a weak spring... you added a shim and it went
up slightly... with enough shims it should be able
to blow the filter apart.... are you sure all the plugs
are in the engine... I forgot 1 in the front behind
the timing cover and it did the same thing
