viair 480c leaking back out?!

[The Big Green]

I can air my truck out and watch it leak down in no time. I may have accuired more leaks but the compressors leaking for sure. Its leaking out the very port it pulls air from. Ive already loosened the braided line and I thought it fixed it so its either Im crazy or it did. I can start with a new line I guess if its possible it just failed. Worse case scenario whats wrong and whats it cost to rebuild it and whats all involved?

It is probably the check valve being jammed in the leader hose. Definitely replace the line and that will fix your issues there. I doubt it has to be rebuilt as they are very reliable compressors, but if it does need it, we can get you the parts.

Give me a call on Monday and I can help you out and get you the leader hose.

Im wanting to say that its 3/4 from the tank and the braided hose is large too. Whatever size it is it was leaking and I tightened it, the newbe in me overtightened it and Im sure thats all it is.

The 480C Will have a 3/8" NPT leader hose. Yes, if overtightened it can jam that check valve. Sometimes they can be saved though. Just remove, re-seal and thread back in. Just snug it in, as it won't take much to seal the threads. If it leaks out of the threads, give it 1/4 turn and check again. Fill the system and see if the check valve is working freely by not letting air back through.

A very good sealant to use is Loctitie 545, instead of teflon tape. If the check valve just won't free it self by removing and re-installing without as much torque, then let me know and I can get you a new one.
