Routing the Airline and Fittings
• Make all airline cuts with a razor or
tubing cutter (part # - 90001081).
The cut must be clean and straight
or it will not seal.
• All
fi ttings are DOT approved
push-to-connect style. They
are very simple to use and are
reusable. Firmly push the airline
into the fi tting to attach. To
release the airline push the collar
on the fi tting back towards the
fi tting and pull the airline out.
•
Use thread sealant on all fi ttings. The white compound that is on the
fi ttings is an anti-gauling compound.
• Do not over-tighten the fi ttings. This could result in breaking the fi tting or
damaging the air spring.
• All of our airlines are DOT approved so they are very strong, but keep them
away from any sharp edges. Also, when passing through a hole in the
frame use a grommet.
• Keep away from intense heat, including muffl
ers and exhaust manifolds.
• Use zip ties or other fasteners to secure the airline.

Mounting the Air Pressure Sensors
• These sensors are voltage based and do not need to be grounded.
• Use thread sealant when installing pressure sensors in valve block.
• Sensors can not be pointed down
( debris can collect and cause false readings)
• The ECU is water proof and may be mounted in the engine bay or under the
vehicle.
• The ECU is a wireless device, do not mount it fully enclosed by metal. Doing
so will reduce the wireless range.
• The Display is
NOT
water proof and needs to be mounted inside the vehicle.
It should be mounted in a location where it can be accessed with ease.
• The Display has a nameplate on the back of the display that can be used
with a magnetic dash mount.
• The orientation of the display can be changed to help tailor it to your install.
• Refer
