Installation Notes and Tips

Inspect the sealing surfaces before installation and replace any O-ring that shows flattening, cracking, or swelling. Clean the regulator and mating surfaces thoroughly, then lubricate the new seals with clean engine oil or approved fuel-system lubricant before assembly. Verify the application against the vehicle service information for the exact fuel system configuration.
