Lookin for someone to guide me threw the process. in person..

Will pay you to help me set it up.
from what i have researched, parts are less then $100, If you've done it before, PM me please!:cheers:
 
I'm slowly working on it. I priced out EVERYTHING and it came out to 82bucks with oiler, filter, and water filter. Hose front to rear with 3gal tank
 
Nick, as soon as you finesh it up, wanna help me get the parts together and talk me threw the setup a little bit. i imagine i can get everything but the tank right there at your job?...
 
I did this years ago and it has been one of the best mods I have made to my Jeep.
There should be plenty of info in the search tech areas. It is a VERY simple upgrade. Originally I did it with no tank and it worked great. I now have it attached to both my front and rear bumpers (about 12 gal total). Works even better. I think it cost me about $45 when I did it originally with no tank and no pressure switch. When I added the pressure switch I think I paid about another $25 or so. I would be shocked if it couldn't be done for less than $100 with all new parts.

If there isn't anyone else in the Portland area I don't mind assisting however it would be best for the group.

Michael, are you running air hose straight off the outlet port? Has heat build up been an issue?

I've heard of hoses bursting from too much heat.

My friend just put one together and he has a plastic coil up hose for now. After filling up one small trailer tire the hose was very hot! I think quite a few people use copper tube to disipate heat.

When you say straight off the outlet port I assume you mean after the pressure valve, over pressure valve, multiport (for a tank, and pressure gauge), filter, etc? Yes, I used to run mine from the outlet port strait through all of these compoents (all brass) and then strait out to a hose, I split a couple of cheap hoses and connectors when I first did it due to heat. I replaced them with better hoses and connectors (quick connectors) and haven't had any issues at all for probably a couple of years. The key is really useing a decent hose and connector and not useing a hose barb with clamps and cheap hose right close to the outlet.

That's what I've heard of as well from write-ups I've read. For heat dissipation people will run copper tube for the first foot or so.

When I said outlet port, I meant directly from the outlet of the compressor.
 
On the oulet of the compressor you need several parts prior to your hose connection:
1. one way valve so that it doesn't damage the compressor
2. safety valve so that you don't run your pressure too high (I think mine is 120psi)
3. a gauge so you know what pressure your at.
4. quick disconnect to connect your hose or tank if you are useing one.
5. pressure switch if useing one.

Then if you are not running a tank you would hook up your hose after these few items. Running a coper tube would be a pain in the ass since it is solid and could easily get damaged. I just run a decent quality hose on a disconnect and haven't had any issues at all.

I think we're both talking about different things. ;)

My question was regarding the line you used between the compressor outlet, and the components you mentioned (check valve, safety valve, etc.)

This guy (T&A-XJ) ran rubber hose straight from the compressor.

This guy ran some copper and brass first.

mine kinda looks like the 2nd example. copper first is the way to go
 
Michael, you should give us all a shopping list and come on down and do a weekend clinic. with 8-10 guys at say $5.0 or $10.00 bucks a piece for your time and trouble.

? ? ?
 
michael being?

Smitty: PM box is full...

Mojojo: I like your idea, i would be willing to chip in if he came down to help a group of us.

Honestly, im willing to pay a knowledgeable person to get me from A-Z, im a complete NOoB when it comes to OBA, im just sick of driving on 10psi tires all the way to the gas station, it would be alot easier to do it trailside.
