3.1 Running & Securing the Air Line to the Axle
IMPORTANT :
The path taken by the air line from the compressor to the Air Locker is unique
to each vehicle and the desired position of the compressor. Plan ahead
carefully when running the air line and always follow these guidelines:
NOTE : The flexible 5mm air line described here is supplied with each Air Locker kit
and NOT with this ARB compressor kit. If you require air line to complete
this installation then contact your ARB Air Locker distributor.
F 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. (Not necessary on IFS installations)
F 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 the flexible brake lines will account for axle
travel and should help keep the air line from getting snagged.
F 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.
F Make sure the air line does not contact sharp edges or abrasive surfaces that may
damage the tubing over time.
F Do not run the air line around tight bends which may kink the tubing and restrict or block
the air flow.
F Keep the air line well away from the vehicle’s exhaust components. Air lines will melt if
subjected to extreme heat.
F Do not run more air line than necessary. Excess line volume created when coiling the left
over hose or using unusually large diameter hose, etc., will increase drain on the
compressor resulting in the compressor running more often than needed.
F Support and secure the air line by tying it back with cable ties wherever possible
(e.g., at least every 40cm [15 inches] along the loom).
F At the solenoid end of the air line, always trim the line to length with a sharp knife to avoid
distorting the tube where it plugs into the push-in fitting.
F 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; while holding the flange of
the fitting out, push the air line into the fitting as far as possible, then press
the flange inward, then pull the air line free of the fitting.
