On Board Air is finally done

I spent the earlier part of today plumbing the pump, routing hose, and plumbing the tank. I didn't get my manifold yet so I can't finish it until next weekend. I've got some pics though. I'll try and remember to edit the first post when I get done so all the pics are in one post.


First is just the mounting of the york. I've had that mount done for quite a while, but another pic or two belongs in this thread.








Next is the plumbing off the york. I drilled and tapped the york fittings to 3/8 npt as those fittings are expensive if you buy new ones. Worked fine. I installed the intake filter on a 90 off the pump. I used 3 feet of coiled 3/8 copper line on the outlet to cool the air before it hits the coalescing filter. I can easily remove the canister on the bottom of that filter to empty it. Off that filter I have a check valve, then the hose runs around the firewall to the other side, where the manifold will be. I just used 3/8 rubber air hose and barbed fittings. The manifold will have a barbed fitting with 3/8 hose to connect it with the air tank, a pressure switch, blow off valve, connection for the inside gauge, and a gauge on it.








Last for now is the tank. It's a 3 part tank, joined with hose on the top as you can see. It has 3 holes on the bottom so I put 2 drains in and 1 blow off valve. I ran hose out the back of it for the intake. The hose on the top will run to the front bumper. It's all done besides some paint touchup, I didn't get real fussy there...











Here's the front bumper air hookup. I used holes that were already in the bumper and just bolted some flat iron on and extended it down. Welded a coupler in it and attached things. The rubber cover is an extra I had for the remote battery terminals, fits perfect.





Gauge on the inside is done. Wires aren't hooked up in this picture, but are now. It's kind of a cluster down there, but there is plenty of room to get to the 4x4 shifter if needed. It's not as close as the picture looks. There is a good 3 inches of clearance above the shifter. I just don't have anywhere else to go with gauges for now. I'm putting a little flush mount switch in that's not here yet.





Here's an exciting picture. That's where the manifold will be.





OK, I got the manifold mounted and plumbed. It has the inlet on the side, and the top 5 outlets are 1 line to the tank, pressure gauge, line to inside pressure gauge, pop off valve, and pressure switch. I mounted it where the battery tray mounted on the drivers side. Worked out pretty good.


























Here is the switch in the cab. I kept it out of the way.





Everythings done except putting the belt on and oil in it. Test tomorrow.

Thanks Glenn. I'm gaining! I'm gonna hook up the gauge and wire the switch in the truck today, then about all I have left is mount and hook up the manifold when it gets here. I checked the tracking on that, it should have been here friday, but is sitting in sioux falls..

Do you have an air ride suspension or something? What CFM does that put out?

The york compressors are known to keep up to impact guns, but I guess it all depends on what the rpm of the pump is running at. There is a few different sizes of pumps available as well.

Looks good Darin. I hope to do this some day. I want to delete the midship tank and put an air tank there.

I guess I'm not positive on the cfm, but I'll use it at the race track, and a little bit for work. No air ride on my truck, just a stiff ride. There will be more times I'll use it too, now that its there, I know I can use it. Basically just copying the Jeep and other guys setups for offroading.


I'm going to edit the first post with a couple more pictures.

Seriously? 4-5 CFM at 90psi?!?!?!?!?

Now that is a some nice work! Onboard air could really come in handy. I must say I am mildly jealous!

yes. There's 2 reasons why people use these pumps. Output and reliability.
