Install The Tire Inflation Kit With The 2MC Air System
This brief article explains how the tire inflation kit can be installed onto our 2MC kits. These kits feature our 2MC air source kit — a 2-gallon tank with an air compressor mounted on top of the tank.
Tools needed: adjustable wrench / wrenches, and a 6mm allen wrench (9/16" may be too small)
Overview
This brief article serves to explain how the tire inflation kit can be installed onto our 2MC kits. These kits feature our 2MC air source kit, a 2-gallon tank with an air compressor mounted on top of the tank. Let’s get started.

Getting Started
1
Locate the flush-mount plug
Let’s get started by locating the 1/4" flush-mount plug on the side of the tank. The plug can be found in between the safety blow-off and drain cock fittings.
2
Remove the flush-mount plug
Using the 6mm allen key, place the short end of the wrench into the hex key. This plug is sealed in with thread-locker and will be very tight. This is normal. Position the allen key so that it points towards the left, or #9 on a clock. You can use your hand or a rubber mallet for the next part. Hit the allen wrench downwards (towards the floor, or #6 on a clock) with some force. This will break the plug loose so that you can loosen it up easier. You may have to hit it a few times to break free. Once loose, continue to turn the plug counter-clockwise until it comes out of the tank.
Plumbing (Tank Side)
At this point, the hard work is over and the rest is fairly simple.
3
Locate the compression fittings
Start by locating the two 1/4" NPT × 1/4" compression fittings that came with the inflation kit.
4
Plumb a compression fitting into the tank
These two fittings will be used to bring line out of the tank and into our air chuck. Let’s start by plumbing one of these fittings into the tank.
5
Tighten and expose the barb
Make sure this fitting is plumbed in nice and tight. Use your adjustable wrench and rotate the fitting at least once clockwise to fully tighten it up. Go ahead and remove the ferrule (nut) from the fitting to expose the barb.
6
Slide the nut onto the air line
Take the nut and slide it over the air line before you press the line onto the barb fitting. Make sure the threaded side (female) of the nut is facing towards the fitting/tank.
7
Seat the air line on the barb
Firmly press the line over the barb fitting. Ensure the line is fully seated around the barb. You don’t want it sitting on there halfway. The image below is a good example of how it should sit.
8
Tighten the compression nut
Go ahead and slide the nut up to the fitting. Tighten it up by hand, and use the adjustable wrench to finish tightening the fitting up.
Plumbing (Air Chuck)
Let’s start by putting this assembly together. Locate the L-shaped mounting bracket and air chuck. You will also need the second compression fitting.
9
Review the assembly order
Check out the image below. These three pieces will go together in this order.
10
Plumb the fitting into the chuck
Plumb the compression fitting through the bracket and into the air chuck. Make sure to wrap the compression fitting with Teflon tape otherwise it will not tighten up into the chuck very well.
11
Connect the air line to the chuck
The compression fitting will hold the chuck in place on your bracket. You may need to use an adjustable wrench to fully tighten the fitting up. At this point, go ahead and remove the nut from the compression fitting and plumb the line onto it like we did for the tank.
12
Mount the chuck and connect the coil hose
At this point you’re almost done. Locate a suitable spot to mount your chuck, and use two screws through the bracket to secure the mount. We usually see the air chuck mounted on the bumper near the license plate for easy access. Your 30′ coil hose can be hooked up to this coupler to provide air for inflating tires, toys, or other inflatables.
