FUEL LINE BLEEDING
Note. Fuel line bleeding is necessary if fuel/water separator filter is not filled before installing, fuel injection pump is replaced, high-pressure fuel line connections are loosened or replaced, or initial engine start-up after engine is not operated for an extended period.
- To bleed low-pressure fuel lines and fuel filter, open fuel bleed screw on banjo bolt. (Scheme 25)
- Operate hand lever on fuel lift pump until steady fuel stream flows from fuel bleed screw. Tighten fuel bleed screw to 72 INCH lbs. (8 N.m). If hand lever feels like pump is not operating, rotate engine 90 degrees and repeat procedure. Position hand lever in upward position once fuel line is bled. CAUTION: Fuel lift pump hand lever must be in upward position once fuel lines are bled to provide proper engine operation.
- To bleed high-pressure fuel lines, carefully loosen high-pressure fuel line nut at fuel injector. Operate starter until fuel flows steadily, and tighten high-pressure fuel line nut to specification. See «TORQUE SPECIFICATIONS»(ref-10657-S21705618302000111300000) table at end of article. CAUTION: DO NOT operate starter for more than 30 seconds. Allow 2 minute intervals between starter operations.
- Start engine and repeat procedure on all fuel lines, one at a time, until engine operates smoothly.
