I'm getting ready to install a Viair on board air kit. It's got a 2.5 gallon tank and a 450c compressor. Heres a link. http://www.suspensionconnection.com/...con/10007.html (P.S. it was an extra 10% off, ends today) It will be used for my us gear decelerator, an air horn, and filling the occasional tire and using the occasional air tool. Eventually I'll use it for some air bags on the back too...

My questions:

Where should I mount the compressor?
Where should I mount the tank?
Where should I get the hose and connections for sending air to the horn, brake, etc.?

Any other helpful tips for installing the kit, now that I finally have it on it's way?

Thanks.

Allot of folks mount the compressor in their toolbox in the bed, if you have one. I think they offer instructions on mounting the compressor on the engine if I remember correctly. The tank can go just about anywhere. You can go by a big rig parts store for the air line supplies.

i plan on mounting my tank under the passenger side door between the frame and body i will be making a skid plate for it, the compressor i'll be mounting in the engine bay bolted to the firewall or I was looking at the space infront of the rear tire lots of air and space there.

I'd say compressor in engine bay and tank underneath truck. Air line is probably cheaper than power wires. Probably get air lines from local hardware store. You can also run a line from the tank and mount it in the bed (or wherever is most convenient for you) with a quick connect on the end. This will give you a very accessible point to hook another hose to air up tires, run tools, etc.

I mounted my compressor behind the cab under the bed on the outside of the passenger side frame rail. And made an enclosure for it out of some leftover alum diamond plate I had laying around. I mounted it up as high as possible and it is completely protected.

I mounted the tank below the rear crossmember under the bed above the drive shaft. There is plenty of room for 2.5 gal tank there.

As far as hose and fittings I just used high quality rubber type hose 3/8' with barb fittings, adapters etc that I got from home depot. The hose has been there over 100k now and no problems with it.

I would also recommend putting in a line to a quick connect that is easily accessable so that you can air up tires, the fishing float tube, air mattress etc. I have mine up front under the bumper as I just t'd off the line by the horn. In retrospect I should have run one to the rear or an additional one to the rear to make trailer tires easier to get too. Instead (after I figured out my hose wouldnt reach the trailer from the front) I just bought an additional hose (the coil up type and when I need to do the trailer I just add it on to the end of my other coiled hose that I keep in my tool box.

A couple of illustrations for hooking everything up that may be helpful

I've heard having the compressor anywhere but in the cab will allow it to suck in water, causing failure....

Is this true?

I'm thinking of putting the tank on the frame somewhere (as mentioned above) because I have the spare in the stock space. Thanks for the info...

Keep the help coming!!!!

can run a hose from the intake to a dry place where you like it to be ED

Suggestions on where to put it?

Thanks.

I am thinking maybe in the openings for the tie downs for the bed and with a u in the line so water can't get to the tube, would be nice in the cab but that would be noisy. I can follow the rear end breather line that is used to allow for air to move in and out of the rear end with out drawing in water. Ed

You might try running the intake hose up to the engine bay. There would be lots of places under the hood where the hose end could be placed which should remain dry.

I have my compressor mounted almost directly over the rear axle, and the suction line ran into the cab with the filter on the end. It is not noisy at all. Can't even hear it run while driving.

Hello all. Well I have been working on my set up for the last few days. I made a mount out of 1/8" plate steel for my five gallon slim line tank. Mounted my horns. I was going to put my K5la on the truck but didn't want to loose the spare. And didn't want it in my bed because I work out of my truck. I used another set of horns, that I had laying around in the garage. They are the black ones that Hornblasters sells under their name. But they are actually made by a company named Buell. I still have to make the mounts for two Viair 450c's, and wire everything up. I know alot of people are having a hard time mounting stuff on a Gen 2, because of the limited room. But I was able to shoe horn all the stuff in. And without removing the spare tire. I'll try to take some pics and post.

I've installed pac brakes big exhaust brake on a 2nd gen, it comes with the tank 5 gal i think and the pump to run the brake. As per there instructions I mounted the pump in side the crossmember under the box. It under the middle of the box and its a c channel. Seamed like a pretty safe spot to me unless your in lots of mud, as the mud would get up there and stay there. The intake was run up under the hood and they supplyed a small filter for it to keep dirt out. The tank was mounted under the right front cab door and it was bolted to the frame. I personally would consider mounting the pump under the box or under the hood, under the box would be quieter but more road debre . I would probably run the air intake into the cab first and see if it was noisey, if its noisey then it would go under the hood, with a few loops in the line to catch water. hopefully this helps a little.
