Porter Cable C3151 compressor

Outlet pressure gauge doe not climb beyond 60psi regardless of what I do with regulator. Gauge returns to zero when the tank is empty. Its hard to tell if there are leaks. Could it just be the regulator?

Hey edmoe,
It could be the regulator ..if the air compressor pumps up and shuts off ok..its the regulator [unless your gauge is bad.. if you can tell your getting the full pressure out and it still reads low]..part # Z-A13369 reg assembly available at ereplacementparts.com... as far as the air leaking out as it sits..you can use a soapy solution in a spray bottle to check fittings etc for air leaks..
Hope this helps..

Thanks cmoorejack. The regulator seems to turn down o.k. but doesn't go high. I have the same problen with a pancake compressor.

what i had on one was the compressor wouldnt turn off or go past 60 some lil metal diaphram thing was broke had it repaired 40$ on my regulator problem if it dont pump up past 60 i open the lil black box and adjust limit scews to get it up to about start 80 - 120 kick off very dangerous thing too do could blow tank if u dont adjust correctly

Where was the "lil metal diaphram"?
