For those with remote QD OBA connections - Mount location and hose route
I am finishing my OBA install and have a few questions for those who have installed front & rear quick disco for the air hose..
- Where did you mount the QD?
I am considering inside in each front foot well; on the front and rear bumper; Or tucked up under the side rails someplace. I don't do any rock crawling, mostly dirt and sand to the concern of tagging them is not high. Inside would keep the connectors clean but that means the doors have to be open to connect them.. Front and rear seems to the the easiest and straightest run. For the rear, I can tuck it up close to the rear hitch receiver for protection. Again, I am not concerned about hitting it on anything.. no big rocks in my immediate future.
- How did you route the hose?
I've seen installs with the hose through the firewall for the inside setups, run through the frame rail and zip tied to the frame rails for the front and rear. Any other suggestions?
- What kind of hose/fittings did you use?
I was originally going to use Purvex press connect hose fittings. But not sure if there is any benefit in using them over standard brass fittings. I need only one elbow, a tee and two connectors for the QD chucks. Seems easy enough to buy some bulk air hose and a few fittings at Lowes or Home Depot. Compression fittings are strong and easy. I was looking at the kits on Dominion Offroad and it looks like someone makes a small diameter hose that accepts compression fittings. That would be easy to route.. Any idea where to find something like this?
- Do you cover the QD chuck?
Sand and dirt can seize the QD pretty easily. Wondering if it makes sense to cover it with something, or to figure a way to install it pointing down somehow.

No responses so I had to figure it out on my own... So for the benefit of others who do this install....
I mounted the remote pickup on the side of the front frame rail...
It's tucked up pretty high so I am not worried about tagging it. Plus, there is no rock crawling in my near future...
A dust cover prevents...dust. Though that would be more important if the quick release chuck was mounted here instead of the male connector.
I decided to use only the one pickup instead of running a second one to the rear. The coiled Viair hose easily reaches all four corners of the two door.
For the hose, I stopped at a local tuning shop that specializes in air suspensions and bought a short length of stainless braided line to use for the leader hose. The compressor outlet gets REALLY hot and pretty much any hose would be vulnerable to heat failure and the braided line remedies this.
From the leader hose to the remote pickup is a heavy 3/8" vinyl air line hose.
I am going to remove the under-hood gauge since the coiled hose has a gauge on it at the air chuck.
I also relocated the intake/filter to up under the cowl to pull cooler air.
Snipped the clamps off the wire for the compressor and hard wired it using a relay and a-pillar mounted switch.
The red switch on the bottom is wired to the relay and switched power.. I am going to change the power source so that it is engine switched power and not accessory switched since I want it to work only when the engine is running.

Looks very good! Thanks for sharing.
I am still deciding where I'll place my tank. The compressor will be on a Dominion bracket in the engine compartment. The Viair compressor already comes with an output braided hose, even though it is a bit short. But should be long enough to dissipate the heat.
The Viair kit allows to place the air intake far from the compressor. Therefore, I'll most likely put both the air intake and output inside the cabin, just to keep everything clean.
