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:
c 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.
c 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.
c 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 which may arise if the air line has to be removed.
c Make sure the line does not contact sharp edges or abrasive
surfaces that may damage the air line over time.
c Do not run the air line around tight bends which may kink the air line
and restrict or block the air flow.
c Keep the air line well away from your vehicle’s exhaust components.
Air lines will melt if subjected to extreme heat.
c 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.
c Support the air line by tying it back with cable ties wherever possible.
c At the solenoid end of the air line, trim the line to length with a sharp
knife.
c 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.
