Part II: Plumbing and Update

 After getting the York in place, the plumbing and electrical hookup still needed to be done. After talking to Don and Damon and pouring over Kilby Enterprise's website, I set off for the local hardware stores. I found most of what I needed at Home Depot. All the fittings, air hose, and a gauge set me back around $100 after taxes. Here are some of the things I picked up at the store:

3/8" Air Hose, 20' $12	Coalescing Filter, $19	3/8" Male Couplers	3/8" Air Chuck
Various Hose Connectors	Inflator, $19

 About the only things I could not get locally were the pressure switch, a safety pressure valve, a 4-way manifold, and a 1" to 3/8" reducer fitting that connected to the York's output port. These parts were ordered from Kilby Enterprises.

 On the suction side of the York, I chose to get a breather-type filter from Kragen for $10 instead of ordering the $20 type from Kilby Ent. that is enclosed and cannot flow as many CFMs. For the discharge, I went back to the junkyard and got some fittings from 1970's-ear Jeep Cherokees that used the York. You can see the difference between the Jeep style and the Volvo style. The Jeep style is nice because the output is threaded. Their sizes vary and I brought home a 1" and a 1 1/8" fitting. I used the 1" fitting with a reducer to 3/8" tubing as you can see in the middle photo.

The discharge line snakes its way to the driver's side fenderl where I positioned most of my 'hardware'. First in line is the coalescing filter. You can only see the top part of it since the K&N is in the way. After the filter, there is a 4-way manifold. The top mounts the safety valve and the bottom port is used by the pressure switch. The pressure switch turns on at 95 PSI and off at 125 PSI. These values are preset by the switch's manufacturer. I set the safety valve to depressurize the system at 130 PSI. After the 4-way manifold I have my pressure gauge and then another 3-way manifold. From here, one hose runs about 3' to the front of the truck and the other hose travels to the rear bumper.

Under the Driver's Door..

Along the Frame Rail...

And Past the Fuel Tank

Here's a view of the rear air chuck. All I have to do is reach under the bumper and plug in my plastic air coil to air up the rear tires. In the winter I will get a male fitting to keep mud and debris out of the system.
Up front, the air chuck exits in front of the driver's side tire. This connection is really easy to get to because of my bumper.

Update

 I've had the Bronco Air Bracket under my hood for a few months now. It has helped out with small things besides airing up tires after a trail. I've used it every so often to get a few more PSI in my bike's tires. On the trail I also have found it helpful for getting my Queen sized air mattress nice and firm after the Coleman low pressure pump does it's thing. 

 The York was invaluable on two of our recent trips. After completing the Deer Valley Trail, there isn't a whole lot around. There isn't a gas station for at least an hour and coming down the mountain roads with low PSI would make our trucks handle worse than they already do. After we reached the gravel road at 9500', the York aired up my 35" BFG MTs, a set of 33" Goodyear MTRs, and another 4 37" Goodyear MTRs. All 12 tires went from approximately 15 PSI to 32 PSI in under 10 minutes. Two people can work off it at the same time with front and rear air chucks. 

 Onboard air served its purpose again, last week. Exiting the Rubicon Trail at 7 PM on a Sunday night let us air up at the Tahoe side staging area instead of having to drive alone the Tahoe shore looking for air. 

 This product has proved itself in quality and has more than paid for itself in convenience. I will put a new spin on the bracket and pulley as I swap in a Saginaw power steering pump.
