 2. If necessary, assemble the fuel pre-filter (2) according to steps 2.a through 2.d.

  a. Install the new sealing gasket (12) to plug (11). Install the plug (11) onto the fuel pre-filter (2). Tighten the plug to a torque of 23 N·m (204 lb in). 

 b. Install the new sealing gasket (15) onto the connector (16). Install the connector (16) onto the fuel pre-filter (2). Tighten the connector to a torque of 23 N·m (204 lb in). 

c. Install the new sealing gasket (14) onto the plug (13). Install the plug (13) onto the fuel pre-filter (2). Tighten the plug to a torque of 23 N·m (204 lb in). 

d. Install the new filter element (17). For the correct procedure, refer to the Operation and Maintenance Manual, "Fuel System Coarse Filter (Fuel-Water Separator) Filter - Replacement".

 

 

3. If necessary, install the fuel pre-filter mounting bracket onto the cylinder head. Install the fuel pre-filter mounting bracket according to steps 3.a through 3.c. 

 a. Position the fuel pre-filter mounting bracket (10) onto the cylinder head (8).

 b. Install bolts (7) and (9) onto the fuel pre-filter mounting bracket (9).

 

 

c. Tighten bolt (7) to a torque of 44 N·m (32 lb ft). Tighten bolt (9) to a torque of 22 N·m (195 lb in).

 

 

4. Position the fuel pre-filter assembly (2) onto the fuel pre-filter mounting bracket. 

 

 5. Install bolt (1) onto the fuel pre-filter assembly (2). Tighten the bolt to a torque of 44 N·m (32 lb ft).

 

 Note: Ensure the plastic tubing assembly and pipe assembly are installed in their original positions. Failure to connect the plastic tubing assembly to the correct ports will allow contaminants to enter the fuel system. If contaminated fuel enters the fuel system, it will cause serious engine damage.

 

 

6. Remove the plug from the fuel pre-filter base (2). 

 

 7. Remove the cap from the pipe assembly (5). 

 

8. Position the new sealing gasket (3) (not shown) onto the hollow bolt (4). Install the hollow bolt (4) onto the pipe assembly (5), then install the remaining new sealing gaskets (3) (not shown). Tighten the hollow bolt (4) by hand.  

 

9. Tighten the hollow bolt (4) to a torque of 21 N·m (186 lb in).
