- Loss of drivability tied to worn fuel pressure control components
Installation Notes and Tips
Confirm the inlet and outlet sizes before installation: 11.0 mm push-in inlet and 8.0 mm hose outlet. Verify the mounting style, system pressure requirement, and fuel line routing on the vehicle before replacing the regulator. For best results, inspect nearby hoses and connections for wear or leakage during service.
