Product Details

Installation Notes
- Turn off the engine, disconnect the battery where appropriate, and work in a well-ventilated area away from open flames or sparks.
- Relieve fuel-system pressure and place an absorbent cloth beneath the connection to catch residual fuel.
- Compare the replacement connector with the original part, including connector size, gender, hose connection, and mating fitting.
- Remove the old connector according to the applicable hose and clamp arrangement.
- Inspect the fuel hose for cracking, brittleness, swelling, or other damage. Replace the hose or clamp if it cannot make a secure connection.
- Install the replacement connector securely on the fuel line using the appropriate connection hardware for the hose and connector design.
- Connect the fitting and confirm that it is fully seated and locked.
- Prime the fuel system and inspect carefully for leaks before starting the engine. Do not operate the engine if fuel leakage or air intrusion is present.
Troubleshooting & FAQ
What size connector is this?
This is a female 3/8 in. fuel line connector. Verify the size of the original connector before ordering.

What are the signs of a failing fuel connector?
Common warning signs include fuel leakage, a persistent gasoline odor, difficulty starting, engine stalling, visible cracking, brittleness, or air entering the fuel system. Replace components that do not seal securely.

No. This listing is for an aftermarket replacement connector. Confirm the part dimensions and connection configuration against the original component before installation.
How often should the connector be inspected?
Inspect fuel-line components regularly and whenever fuel leakage, starting problems, or fuel odor is noticed. Replace the connector or related hose components if they are damaged or do not seal properly.
