Viair Quarter Duty OBA install

Here's a little build log of installing the Viair Quarter Duty system i just acquired. If anyone has been wanting an OBA setup, this can be had for around $200 shipped from Performance Fueling. Anyway, this won't be finished for another week or so since NONE of the parts stores here in town, or in the next town, have compression fittings of any kind, so i had to order some off the net. I did however get the chance to configure the switch panel in the jeep, mount the compressor, and wire it all up. So, here are a few pictures to show the progress I've made so far.


And for anyone wanting a quick link to specs on this setup, here's the direct link to Viair.

VIAIR Corporation - Quarter Duty OBA Part No. 10002











Also, this is where I think I'll mount the air chuck. Any better suggestions would be helpful, but this seems like the most useful and out of the way place on the jeep.

Any pointers on mounting the tank? The way I'll have it mounted the fittings will be pointed downward. Granted, i wont be rubbing bottom at all (if ever), so its not that big of a concern, but itd be nice if they pointed towards one side so as the tank "bottom" is smooth. And any pointers on where a good/easy to use place to mount the air chuck?

Was going to say, whew, that compressor is smaller than my viair... I had to mount mine where you have your intake installed. Mine is prob bigger because it is the tankless version. I actually routed my intake into the cabin so it wouldn't pull in dusty/wet air or anything like that. Prob unnecessary. I also just left the chuck on the hose and leave it coiled up right there where your tank is installed. didn't want to do any body drilling.

I've already drilled the tub (made my own rock sliders), and I plan on never giving this Jeep up, so drilling a hole or 2 doesn't really bother me. I'm mainly looking for the least amount of work possible to air up a tire. But this is the 275 compressor, which i believe is a little smaller than yours. It was definitely a PITA to get into that position and secure it down, but I'm glad I put it there, up and out of the way. And it just looks clean.

Made a bracket to mount the tank 90 degress from straight down. Because of how the fitting spots were welded to the tank, they would have been hanging straight down, which is no bueno. Built this out of 1/4" steel plate. Used a gas mig to weld it up (havent welded very much, but the beads look nice, and had good penetration). After I drill the mounting holes in the tub I'll be spraying the bracket with bedliner to keep it clean looking. Don't want to rush this install.

DONE!!! Just got the tank installed and everything plumbed. There is a slight air leak somewhere, but it's small enough I can't hear it so I'll just go over the fittings with soap and water next week sometime. VERY happy with how it all turned out, and how well it tucked up under the jeep.

Total cost was:
VIAIR QUARTER DUTY kit: $190 shipped
Misc fittings: $30
Nice 30' air hose: $15
Total: $235

Took about 3-4 hours total over about 3 days to wire, install, and plumb everything.

So before i.left the house i did a little test. My truck has 32" all terrains and one tire has a slow leak and had about 8 psi in it. Even with the slight leak in the air system, and the jeep not running (so compressor was seeing about 11.5 volts instead of 14.0 volts), it took the tire from 8 psi to 25 psi in exactly 1 minute. Needless to say, im.pretty damn happy.
