Information:
1. Remove fuel line (1) from the fuel transfer pump.2. Put caps in the fuel line openings to prevent fuel system contamination.3. Remove bolts (2), and remove fuel transfer pump (3). Check the condition of the O-ring seal on the fuel transfer pump. If necessary, make a replacement.Install Fuel Transfer Pump
1. Be sure O-ring seal (1) is in position on the fuel transfer pump. Put clean engine oil on the O-ring seal.2. Put fuel transfer pump (2) in position, and install the bolts that hold it in place.3. Remove the caps from the fuel line openings, and install fuel line (3).4. Prime the fuel system. See the Maintenance Guide for this procedure.Disassemble Fuel Transfer Pump
Start By:a. remove fuel transfer pump 1. Remove seal (1) from the fuel transfer pump.
Cover (2) is under spring tension. Remove the bolts that hold cover (2) slowly to prevent injury.
2. Remove bolts (3) and cover (2) from the housing. 3. Remove seals (4) and valve (5) from cover (2). 4. Remove spring (6) from the piston.
