Gang,

I have read this thread regarding air compressor problems but have not found my solution Air Compressor Problems

My compressor runs, but does not seem to put air into the system.

Symptoms:

1) Air compressor runs but does not pump up tank.
2) With 120V air compressor "ON" I can completely run out of air overnight.
3) Engine can "pump up" system in a few minutes.
4) The 120V compressor runs for a long time but *does* turn off eventually. (It does not feel hot).
5) If I put my thumb over the outgoing air from the compressor I can feel pressure and hear the pump load up. I let go of thumb and can feel a little air and the pump unloads.
6) If I pull wires from the head pressure relief solenoid with pump running, air is vented from the port. (No air vented with wires attached)

I took the check valve out and blew on one end and then the other. It lets air go in only one direction.

I have included pictures along with a diagram of the connections. Any ideas?

ps. On a side note, is there a problem with using 1/4" and 3/8" tubing? It seems as if the 1/4" would restrict air flow.

Thanks,
bill
