Step 2: Prepare suction and feed lines.

Remove the 3 bolts holding the fuel cooler to the mounting bracket. The fuel cooler is located in front of the fuel tank.

Using a fuel line disconnect tool, disconnect the factory suction line located above the fuel cooler. Place the disconnect tool around the fuel tube and slide the tool under the fuel line connection to release the fuel line.

Pull the red square tab out and push in the rounded tab, releasing the fitting from the steel-beaded feed line.

Using oil, insert PLB-1212 into one end of the provided FL-1002 fuel line. Feed line over frame to the stock fuel connection.

Push the PLB-1212 into the factory suction line until you hear a click and the tabs are locked in place. Slide square tab back in to secure.

Using an HC-1001 hose clamp, insert the QD-1002 into the other end of the provided FL-1002 fuel line and secure.

Oil the rings inside the QD-1002 and slide over the factory feed line until you hear a click. Do not cut the line at this time.
