Installing the AirDog

II Fuel Supply Line to the Engine
To install the AirDog® II fuel supply line to the engine, you must first remove the
(flexible) factory fuel line connecting the fuel tank to the frame mounted steel
fuel line (Figure 17). It will be the larger of the two lines that are on the frame.
NOTE:
The fuel tank connections are located behind the tank shield. It may be necessary to
remove or bend the tank shield down to access the suction tube quick connect fitting
.
6A-1. Remove the factory fuel supply line from the fuel tank suction tube. Place the 1/2”
fuel line disconnect tool around the fuel line and press into the Quick Connect fitting
to release the locks. Carefully pull the factory quick connect fitting and fuel line from
the fuel tank suction fitting.
The DISCONNECT TOOL (as seen below) can be purchased from your local auto parts store.
This
tool is NOT included in the kit.
6A-2. Disconnect the other end of the fuel supply line from the steel line using the disconnect
tool. It is the larger of the two lines on the frame. This connection is located between
the frame bracket and the front of the fuel tank. You may now remove the 18” of
factory flex line.
