on-board air

Since I cant afford a good ARB on-board air kit i decided to make to make my own system. I found some good quality pumps for cheap and air lines are plenty-full for low cost. The toss up i have run into is the air tank size. Primarily i plan to use the system for my tires, tools if needed and some horns ( personal desire on that part lol). I am thinking that a 2 gallon tank will be plenty but before i pull that trigger i figured i would ask opinions to make sure its enough, if i need bigger or if its over kill and can do with something smaller. Any thoughts?

My plan is to have a dedicated air line just for tires and the tank for the horns and air tools. The pump i am looking at is rated up to 1.35 cfm air flow capable of 150 psi, its able to fill 35 in tires in 3 min or less.

I would run an air tank. If the pump is running when checking pressure and moving to another tire. It might as well air up the tank.

If it wasnt for the air horns, id recommend co2. Ive had all the different setups: york, oasis, viair...i ditched it all on my current rig for a 20lbs co2 tank with a 5lbs secondary.

I am using one of the Superflow MV50 compressors... I had one of those harbor freight 2 or 3 gallon oilless compressors laying around that didn't work anymore, so I mounted the MV50 to the tank and piped it in with some 1/4" copper. Works great for filling tires and short blasts of air tools and train horns. Don't plan on running much more than an impact wrench for a few seconds at a time with any electric onboard compressor. Pretty much the only thing that will keep up with prolonged air tool use is a modified York run directly off the engine.

Harbor freight has a coupon out right now for those oilless hot dog compressors for 40 bucks. That'd probably be worth it just for the donor tank. I'm very happy with my air setup considering it cost me under $100

1.35 CFM isn't enough to keep up with air tools even with a 2 gal. tank. You will only get a few seconds of air for them. You would be better off running a smaller tank, such as the 1/2 gal. tank suggested by Frenchie, and buying a battery powered impact wrench. The problem with larger tanks was mentioned earlier - the additional volume is the equivalent of another tire or two, depending on size, so that you are effectively filling 5-6 tires rather than 4 every time you air up - however the larger tank still isn't enough to store enough air to fill a tire. A smaller tank will store enough air for an air horn and provide the necessary buffer to reduce stress on your compressor at start up and allow the use of an on/off pressure switch.

Hadley sells a 1/2 gal. tank, P/N H00626, that measures 5" x 7" (pictured below) and also a 1 gal. tank, P/N H00751N, that measures 5" x 14". I have owned both, The Hadley 1 gal. tank came with an 12v onboard air kit sold by Curry Enterprises in the late 1990's and was mounted in my jeep. It was plenty for my 35" tires and air horn. I acquired the 1/2 gal. tank used from an RV bone yard. It is now mounted underneath my Xterra - the only tank I could find that would fit the available space - and is plenty for 33" tires and air horn.

I've got a 1 gallon tank. With 31x10.50x15 tires, its pretty useless by itself. I've played around with it and it'll barely raise the the PSI for 15 to 20 on one tire. So the compressor runs constantly. Its more like a buffer than anything else. I wouldn't waste your time with anything less than 5 gallons of capacity.

One of those aluminum 5 gal generic tanks would be awesome if you have space for it. Lightweight.

My college roommate put a York on his jeep. Unless you go full on and do everything correctly, it'll never be quite right. Seems like his never worked or all the oil leaked out or whatever the problem was that day. It was also plumed up to his bumpers, which were both air tanks. They worked but had no capacity.

The newer C02 tanks are solid.

I never could get the MV-50 to work. But I know many who have had good luck with them.

I ended up biting the bullet and getting an ARB twin piston. It just works.

Puma PD-1006 capabilities meets your needs -
35" tire 15 - 36PSI = 2:00min each at sea level
Using a 3/8" IR gun you can remove a tire torqued at 105lbs without waiting

Could we see the set up on your X? Or a link to a build I'm interested :)

Lot of good info, I am not opposed to abandoning air tools for electric ones, just thinking of what tools i have now is all. Ill check out the suggested set ups though, wouldn't hurt to have options. I also forgot to mention the air system i am wanting to build will run air lockers.

My 12v puma with a 1.5 gallon tank was enough to run my 3/8 impact gun to remove lug nuts on my tundra.

My 4Runner also has a puma with a 1.5 gallon tank and a 3 gallon remote tank. I charge them up as Im about to pull over to air up. I am able to overfill one tire from 10psi to 45psi in about 30 seconds

You can use an old fire extinguisher or propane bottle or dead pancake compressor as the air tank for free. Scavenge pressure regulators from dead compressors on eBay or craigslist

I am looking at around $140 or less, problem is the existing kits i find for that price range are crap that's why i was thinking of just making my own set up, plus a little pride in saying i made it my self :) lol.
