4.2 Running and Securing the Air Line
The path taken by the air line from your air source (i.e., compressor) to
your Air Locker is unique to your vehicle and the position of your air
source. Plan ahead carefully when running the air line and always
follow these guidelines:
Account for axle travel when running the line from the axle to a
fixed point on the vehicle. Leave enough slack in the air line to
allow for maximum suspension travel in both directions.
Avoid leaving large lengths of air line hanging underneath the
vehicle where they may get tangled on rocks, sticks, etc.
HINT : Cable tying the air line to one of your flexible brake
lines will account for axle travel and should help keep
your line from getting snagged.
Run the air line all the way from the compressor to the differential
before trimming either end of the line to length. This will save
complications that may arise if the air line has to be removed.
Make sure the line does not contact sharp edges or abrasive
surfaces that may damage the air line over time.
Do not run the air line around tight bends that may kink the air line
and restrict or block the air flow.
Keep the air line well away from your vehicle’s exhaust
components. Air lines will melt if subjected to extreme heat.
Do not run more air line than necessary. Excess line volume
created when coiling the left over hose, using unusually large
diameter hose, etc., will increase drain on the compressor tank
resulting in the compressor running more often than needed.
Support the air line by tying it back with cable ties wherever
possible.
At the solenoid end of the air line, trim the line to length with a
sharp knife.
To attach the air line to the push-in fitting of the solenoid; insert the
line firmly into the fitting, pull outward on the flange of the fitting
while holding the line as far into the fitting as possible, and then
gently pull outward on the air line to clamp the line in place.
NOTE : To remove the air line from the push-in fitting; pull
outward on the flange of the fitting, push the air line
as far into the fitting as possible and hold, push
inward on the flange, and then pull the air line free of
the fitting.
