Installation Guide

1. Ensure the engine is off and the fuel system is depressurized before beginning.
2. Identify the correct fuel line size your system uses (either 5/16" or 3/8").
3. Securely attach the female sprayless connector to the fuel hose that runs to the engine. Use a hose clamp to ensure a tight seal.
4. This connector is designed to pair with a male tank connector (sold separately, part number 8838TM6) that fits fuel tanks with a standard 1/4" NPT fitting.
5. To connect, push the female connector onto the male tank fitting until you hear an audible "click," which confirms a secure, sealed connection.
6. Once connected, prime the fuel system according to your engine's manual and carefully inspect for any leaks around the connector.

Troubleshooting & FAQ

How do I know if this connector will fit my fuel line?

Do I need any other parts for installation?
