I have a Porter Cable 25 Gal upright 135 PSI Model # CPF 6025UP.

Motor runs great, pulling air thru inlet but no pressure at all. Checked all plumbing no leaks. I really can’t figure this one out. Ant ideas ?


Hello Joe.

You’ve ruled out the valve issue by checking that the intake port is actually drawing in air and not blowing it back out. That suggests that valve is fine.

Do the same for the line that goes to the tank from the pump head, and be sure that air is being pumped out strongly. Try to stop it with a gloved finger. You shouldn’t be able to.

If there are no leaks, all other things being good on your air compressor as they seem to be, my guess would be a gasket failure under pressure inside the pump.
