INSTALLING THE AIR LINES

When installing the air lines, there must be at least six inches of clearance between the air 

lines and any heat sources.

1.  Choose a convenient location for mounting the inflation valves. Popular locations for the 

inflation valve are:
The wheel well flanges; The license plate recess in bumper; Under the gas cap access 

door; Through license plate (fig. 12).

Whatever the chosen location is, make sure there is enough clearance around the inflation 

valves for an air chuck. 

2. Drill a 5/16 “ hole to install the inflation valves. 
3.  Cut the air line assembly (AA) in two equal lengths.
WHEN CUTTING OR TRIMMING THE AIR LINE, USE A HOSE CUTTER, A RAZOR BLADE 
OR A SHARP KNIFE. A CLEAN, SQUARE CUT WILL ENSURE AGAINST LEAKS. DO 
NOT USE WIRE CUTTERS OR SCISSORS TO CUT THE AIR LINE. THESE TOOLS MAY 
FLATTEN OR CRIMP THE AIR LINE CAUSING IT TO LEAK AROUND THE O-RING SEAL 
INSIDE THE ELBOW FITTING (FIG. 13). 

4.  Install the inflation valves as shown in fig. 14.
5.  Keep at least 6” of clearance between the air line and heat sources, such as the exhaust 

pipes, muffler, or catalytic converter. Avoid sharp bends and edges. Leave at least 2” 

of slack when securing the air lines to allow for any movement that might pull on the air 

line.

6.  Cut off air line leaving approximately 12” of extra air line. Insert the air line into the air 

fitting. Simply push the air line into the 90° swivel fitting until it bottoms out (9/16” of air 

line should be in the fitting).
