Step 3: Mount fuel system.

Using thread tape, install the 10-298 into “E.”

Install the 10-299 into “T” port.

Attach BR-2001 to back of system using 5 1 1/4” Hex bolts and WA-2001 spacers. Torque to 110in/lbs. Use the Hex Bolt 1/4”-20x2 1/4”+WA-1001D spacers on top of the WA-2001 spacers if you need more space between pump and the frame.

Position system to mounting location, drivers side below the bed in front of the axle. Make sure to mark these drill points at least 1” from radial bend of the frame. The radial bend is both the top and bottom of the frame. Note that there is a wire harness on the opposite side of frame rail.

Drill 4 pilot holes. Then drill those holes out with a 5/16” bit for the self-threading bolts.

Before mounting in position, route wire harness along frame rail to mounting location connecting to FASS. Turn key on. With pump operating, liberally spray WD-40 (or equivalent) into “T” port lubricating gear. Using the 4 - 3/8” Self Threading bolts, attach the pump to the frame. Make sure to place the rubber isolator between the frame and bracket.

Apply motor oil to O-rings located on filters. Attach to system. Tighten by hand.
