REGULATOR

high-pressure, fuel pump system that includes a filter and a

NOTE: For all other information related to the EFI
System, refer to Chapter 6.
VENT LINES
1. Check fuel tank, front gear case, rear gear case and
transmission vent lines for signs of wear, deterioration,
damage or leakage. Replace every two years.
2. Be sure vent lines are routed properly and secured with

IMPORTANT: Ensure lines are not kinked or pinched.
