    Parts list looks solid. My compressors don't have an unloading valve to my knowledge. Will look again though.

    Unless the check valve is the same thing.

    The unloader is probably not necessary but It should make my cheap compressor last longer. Now I just gotta find the right combination adapters to make this work.

    Walk into Home Depot with your stuff and sit in the Plumbing section. Start opening all the Watts fittings to make sure everything fits. Collect your pile of stuff, pay and done! Oh, and order the Loctite 545 for yourself.

    Or find a place in your area that specializes in oil, air or semi truck parts. I went to a place called "Williams oil filter". They had a huge stock of fittings and the guys there were very knowledgeable.

    That's the plan!
    No tank right now, but when I get one i'll keep it in mind.

    My local Home Depot and lowes are very lacking in brass fittings. Maybe 2 different T's and no crosses. Also this dang compressor fitting is a weird ass size.

    I'm not sure yet but I'll let you know when I do. I think I need a metric fitting. The 1/4 pipe thread (not tapered) and the 1/4 NPT are both slightly too large.
    Perhaps this http://www.parker.com/portal/site/P...nextdiv=687547&vgnextpartno=222P-4-M112&Wtky=

    Can you guys help me find a source for this or any other 1/4npt female to m12 male adapter. The only ones I've found are $18 dollars after shipping.
    Thanks

    Which pressure switch should I get. I think I remember reading ARB lockers liked the 85psi one. I don't have lockers yet but want one later. Right now Tire fills is all I will be doing.

    Don't worry about low psi switches. That's what regulators and solenoids are for. Get something similar to what your pump or rated at.

    I cut mine open and disassembled the whole thing. Took the Relay out, and removed the pressure switch.

    Ran wire up to the engine bay to my RFRM, have it relayed and fused in there. Grounded near the compressors.

    check out my build
    After the last wheeling trip, I though my Viair 450C compressor was done for. There was power going to the compressor from the pressure switch, but no movement.

    But check this, I switched the + and -, so I hooked up the black wire to power, and grounded the red wire, and it started to work in reverse. Then hooked it back up the proper way and it started to work properly! It's like it seized up, and needed to go in reverse for a sec, then started to work fine. Weird eh?

    Debris might have gotten in there. Or moisture but you're right it sounds like it seized up
