Installation Notes and Tips
Confirm the inlet and outlet port sizes before installation and verify the regulator matches the vehicle’s fuel system layout. Inspect connected hoses and fittings for wear, and replace any damaged sealing surfaces before final assembly. After installation, check for leaks and confirm fuel pressure is within specification for the application.
