Information:
1. Turn the fuel supply line valve to the "OFF" position.2. Remove tube assembly (2) and tube assembly (4).3. Remove bolts (1) and (5). Remove fuel transfer pump (3). Remove the O-ring seal from the fuel transfer pump if necessary. Assemble in reverse order.Disassemble And Assemble Fuel Transfer Pump
Start By:a. remove fuel transfer pump
Keep all parts clean from contaminants. Contaminants put into the system may cause rapid wear and shortened component life.
1. Remove bolts (2) and cover (1) from fuel transfer pump housing (11). Remove seals (5) and (6), and valve (4).2. Remove spring (3), washer (7), valve (13), seal (8), sleeve (9), and piston (10). Remove seal (19).3. Remove seal (14) and guide and tappet assembly (12).4. Remove screw (17), cover (18) and seal (16). Remove valve assembly (15).5. To assemble fuel transfer pump, install valve assembly (15) in the fuel transfer pump housing. Lubricate seal (16) lightly and install it with cover (18) and screw (17).
The tappet and guide of the guide and tappet assembly must be serviced as a unit.
6. Install seal (14) and guide and tappet assembly (12) in the fuel transfer pump housing.7. Install seal (19) on sleeve (9). Install piston (10), sleeve (9), seal (8), valve (13), and washer (7). Install spring (3).8. Install seal (5), seal (6), and valve (4). Install cover (1) and bolts (2).End By:a. install fuel transfer pump
