Just wonderin if anybody does. I have been thinking about it. Maybe a to a 5 or 7 Gal tank and pre filling it at the gas station before I go out Wheeling and have the ARB back it up. I did a search but didn't see the answers I was looking for. How much air time would I get out of a 5 or 7 Gal tank?
Thanx in advance

The ARB compressor is not a continuous duty pump, and lucky if it does >1CFM over 20psi (read: You'll kill the little turd in a hurry filling a 5 gal tank). I burned up a QuickAir II in about a year, providing air for an ARB locker, 2 gal tank, and refilling my club's tires at the end of the day.
Best bet is go with a York (or similar) compressor. Many, many, write-ups on the Web, and this BBS on the how-tos.

FWIW, there's a thread on the Jeep Forum discussing 12v compressors; folks talking about getting creative with multiple 12v compressors. Hell, if I can fit a york under the hood of my ZJ, you can surely find room in your pickup's compartment.

I ahve about a 2-3 gallon tank and it takes about 7 minutes of the compressor to charge it up to 90 psi (I think that's what the switch is reg'd at). Even with the bleed off at the pump, that air supply lasts me about and hour of off and on use. I'm going to plumb my SCUBA tank ino the system and use the compressor as a backup, just to keep it from working so much, plus the air from the SCUBA tank is filtered and dry, so no worries of contaminants.

If I prefill the tank at a gas station or somewhere else at 125-150 psi will I need some kind of a check valve for back pressure to the ARB comp?
What is the continous duty life of an ARB? 1/2 hr or so till it gets to hot?
I prob will get a york eventually or something similar I saw a post when I did a search about compressors that someone used a compressor off an older chev that fit right into factory brackets and had similar results as a york, or I could just fab a mounting kit for the york. I am looking for a quick cheap fix right now something to get me thru till I add an ac comp. After all I will need the tank and fittings for the York or whatever I choose.

100psi max. for ARB's. I guess you could put in a regulator set @ 90. If you have no leaks, 5 gal. would probably last all weekend.

if you are looking cheap, look for a cheap caddy compressor. I have a caddy as an electric backup to my york and its slow but it does work.

I don't have the link handy, but hit www.4x4wire.com/toyota and there is a writeup for a 56 buck ARB compressor. This included fittings and a pressure switch etc.

Pumps go for about 10 bucks in yunkyards.

Thanx for all the info guys, but the info I really need is if I can hook up the air tank to the ARB comp and how long it will last.
Wilson and cbassett's answers were along the lines of what I'm looking for.
Can I hook up the ARB comp to a tank to just fill tires and run tools? And still have a separate line to the locker? I would like to be able to prefill the tank to a higher psi and have the compressor kick in when it gets low.
thanx again

My ARB pumps up a 2.5 gallon tank, , takes like 5 mins to fill it, i dunno, i turn it on when i start the truck the day before a trip, Mine last all day, and will hold the psi for about 3 more days. my shit don't leak

My experience is pretty similar to Welndmn. I have a 2.5 gallon tank plumbed directly back to the arb compressor. It takes less than five minutes to fill and lasts at least a dozen engaged - disengaged cycles. Then it takes about a minute to get back up to full pressure. It will drive an impact wrench for short periods but doesn't push enough air to run a cut-off wheel for more than 20 seconds at a time. I use it to fill tires, but it is slow and heats up over time. I usually fill up just enough to drive stable on the road and fill the rest at the nearest gas station. I've had this set-up for about six years without any problems.
Just recently I added a York and plumbed it in to the same tank. I added a pressure regulator between the arb and tank so that i can use a separate pressure solenoid for the York that is rated up to 150 psi. Now I have a fast way of filling tires, can run air tools, and have a back-up system if the arb goes south on the trail.

Shipwreck or anyone else know where can I get all the goodies to hook up this system at a good price, mainly pressure regulator and solenoid?


How easy is the york to hook up? I know they can be gotten fairly easily. I am going to make it one of my summer projects. There are tons of write ups about them. What is the "wrench" Rating?

Adding a York can be easy or it can be more complicated; just depends upon what you want to do and how sophisticated your system is. The hardest part for me was making room under the hood and fabbing the bracket for the York. Most of the plumbing can be found at the local hardware store. Read the tech articles, figure out what you want to do and go for it.
Here is the regulator I used. It is compact and cheap:

The air solenoids for the ARB system can be found at MAC valves. I don't have the part #, but if you do a search here I'm sure you can find it.

onboardair.com (http://www.onboardair.com) also has supplies and links to good info.

Hey thanx alot shipwreck and others, info much needed. I'll give those sources a try.
