INSTALLING THE AIR LINES
1. Choose a convenient location for mounting the inflation valves. Popular locations for the
inflation valve are:
a. The wheel well flanges.
b. License plate recess in bumper.
c. Under the gas cap access door.
d. Through license plate itself.
What ever 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. 3)

4. Place a 5/16
"
nut (GG) and a star washer (FF) on the air valve. Leave enough of the
inflation valve in front of the nut to extend through the hole and have room for the rubber
washer (EE), flat washer (DD), and 5/16
"
nut (GG) and cap (CC). There should be enough
valve exposed after installation - approximately 1/2
"
- to easily apply a pressure gauge
or an air chuck (fig. 4).
5. Push the inflation valve through the hole and use the rubber washer (EE), flat washer (DD),
and another 5/16
"
nut (GG). Tighten the nuts to secure the assembly in place (fig. 4).
