• Fuel system service on gasoline-powered classic vehicles

Installation Notes and Tips

Verify inlet and outlet orientation before installation, and confirm the vehicle uses the correct 3-line pump configuration with air conditioning. Check the 5/8-18 UNF outlet connection and 0.375 in. inlet size against the existing fuel lines before assembly. Prime the fuel system and inspect for leaks after installation.
