Installation Notes and Tips

Verify inlet and outlet port sizes before installation: 16.0 mm push-in inlet and 9.0 mm hose outlet. Confirm the vehicle uses a 43 psi fuel pressure specification and a bolt-mounted regulator location. Inspect connected fuel lines and seals during replacement to help prevent leaks and ensure proper fuel system operation.
