Hardware List
IMPORTANT NOTE:
Depending on the orienta-
tion of the tank once it is mounted, the fittings may
go into different ports on the tank. The drain valve
must always be put into the port facing downwards
(Figure 2).
IMPORTANT NOTE:
Apply the provided thread
sealant to all of the air tank fittings that have not
been pre-coated with sealant.
1. Attach the two air fittings to the ports on either end
of the tank (Figure1).
2. Choose a mounting location for the accumulator
tank.
NOTE
: Be sure that there is ample room for the
air lines and that they will be clear of any heat
sources.
3. Attach the swivel elbow fitting to the port on the
expansion tank that will be facing upwards once the
tank is mounted (Figure 1).
4. Attach the drain valve to the port on the expansion
tank that will be facing downwards once the tank is
mounted (Figures 1 and 2).
5. Attach the plugs to the two remaining ports on the
expansion tank (Figures 1 and 2).
6. Attach the tank to the chosen mounting location
using the provided bolts, flat washers, and nyloc
nuts (Figures 1 and 2).
Attaching the Air Lines
1. Deflate the rolling lobe air sleeves and disconnect
the air fittings from the sleeves. Remove the
existing air fittings from the air sleeves.
2. Attach the supplied 90° 1/4” x 1/2” air fittings into
the air ports at the top of the sleeves (Figure 1).
3. Connect a length of air line from one 1/2” air fitting
from the expansion tank to the fitting in one of the
sleeves (Figure 1).
4. Connect another length of air line from the remaining
1/2” air fitting from the expansion tank to the fitting in
the other sleeve (Figure 1).
5. Attach the 1/4” air line from the existing tee for the
manual fill valve to the elbow on the expansion
tank (Figure 1).
6. Turn the key on and let the suspension resume ride
height. Check for leaks.
