FP-100

6D-1. Remove the original fuel suction line Quick Connect fitting from fuel tank by squeezing

the tabs on the end of the connector together and removing the factory suction line

connection. Consult factory manual if unsure. Very Important: After removing the

factory line check to make sure that the blue plastic retainer was removed with the line.

If the blue retainer remained attached to the tank tube, it MUST be removed before the

new fuel line Quick Connect will connect and seat to the tank suction tube. The original

suction line can be tied out of the way or removed.

6D-2. Assemble one end of the hose (Reference section 5) using fuel line end FCQ38S and plug

it into the male connection to where the factory suction line was just removed in the

previous step. A “click” will be heard once properly connected.

6D-3. Run the fuel line along the frame as mentioned in step 5-3 to the AirDog® “Fuel In” port.

Cut the fuel line to length and insert fuel line end FQC12S per step 5-1. Once the fuel

line end is pressed in, connect it to the male J2044 fitting in the AirDog® “Fuel In” port.

A “click” will be heard once properly connected.
