or in a vented storage compartment. (Note: The compressor can be mounted in
any orientation.)

Using the compressor feet as a template, mark and drill three 1/4" holes. Any

burrs in the holes should be removed to prevent damage to the rubber isolators.
Mount the compressor using the #10-32 x 1" machine screws, #10-32 lock nuts,
and #10 washers supplied with the kit see Figure "B". Maximum vibration
isolation can be achieved by properly mounting the compressor. The machine
screw and nut should be tightened only enough to bottom-out the brass insert see
Figure "B"
. DO NOT OVER-TIGHTEN. Over-tightening will crush the brass
insert and the insulator, thereby reducing vibration isolation.

TANK

ATTACHMENT

Select a location to mount the air tank. This should be in a protected location

to prevent damage from rocks or airborne debris. Mark and drill two 7/16" holes
2-1/2" apart. Bolt the air tank in place using the 3/8" -16 x 1-1/2" hex bolts with
the 3/8" -16 flanged lock nuts and 3/8" washers provided. Ensure that the
installation allows unrestricted access to the air ports on the tank.

PANEL

ATTACHMENT

Select a mounting surface for the gauge panel under the dashboard of your

vehicle or other protected location. Using the gauge panel as a template, center
mark the mounting holes on the dashboard. Drill a 3/16" hole on each center mark
see Figure "D". Do not attach the panel to the dashboard at this time.

Cut a piece of air line tubing that will reach from the gauge panel mounting

location to the air tank. Insert the end of the air line tubing into the T-fitting on
the back of the gauge panel. Route the air line from the gauge panel to the air tank
see Figures "A" & "C". It may be necessary to drill a hole in the fire wall to route
the air line. Make sure that the air line tubing is protected from sharp edges. Insert
the other end of the tubing into either push-to-connect fitting on the air tank.
Secure the tubing to the vehicle with the provided nylon ties. Do not fold or kink
the air line tubing.

Cut a piece of air line tubing that will reach from the air tank to the

compressor. Insert one end of the air line tubing into the brass T-fitting on the
compressor. Route the tubing to the air tank, avoiding sharp edges and direct
heat. Insert the other end of the air line tubing into the remaining push-to-connect
fitting on the air tank see Figure "A". Secure the tubing to the vehicle with the
provided nylon ties.

SPRINGS

Cut two lengths of air line tubing that will reach from the gauge panel to each

of the air helper springs. It may be necessary to drill a hole in the fire wall to allow

the air line tubing to reach the rear of the vehicle. Ensure that the air line tubing is protected from sharp edges. Before installing
the tubing to the gauge panel, soak one end of the tubing in hot water for a few minutes to soften the tubing. Slide the tubing onto
the barbed fitting on the back of the gauge panel as far as possible. Do not use pliers to work the air line onto the barbed fitting,
as the tubing may be damaged.

Install the other end of the air line tubing into the push-to-connect fitting on the air spring see Figure "A". Insert the tubing

as far as possible into the fitting. Route the tubing to avoid sharp edges and direct heat from the exhaust system. Secure the tubing
to the vehicle with the nylon ties provided.

INFLATION

VALVE

Cut the air line tubing in a convenient location between the gauge panel and the air tank. Install a push-to-connect T-fitting

between the gauge panel and the air tank see Figure "A". Select a location on the vehicle for the manual inflation valve. This
location can be anywhere on the chassis of the vehicle, as long as it is in a protected location so the valve will not be damaged,
but maintain accessibility for the air chuck. Drill a 5/16" hole and install the air inflation valve using two 5/16" flat washers per
valve see Figure "F". Route the air line tubing from the T-fitting to the inflation valve. Avoid direct heat from the exhaust pipe
