Troubleshooting & FAQ
How do I confirm this connector is the correct replacement?
Compare your original connector with the photos and specifications, then verify that it is a 3/8-inch female engine-side connector and that your existing part matches Mercury 22-13563A3 or 22-13563Q3. Also confirm the locking and mating arrangement before installation.
What are common signs of a failing fuel connector?
Common symptoms include fuel leakage, a gasoline odor near the engine, hard starting, stalling, sputtering, a loose connection, or a connector that no longer locks securely.
Is this the engine-side or tank-side connector?
This is the female engine-side fuel connector. It mates with the compatible tank-side connector arrangement; engine-side and tank-side connectors should not be assumed interchangeable.
Is this an OEM part?
This is an aftermarket replacement connector. Sierra 18-8076 is listed as a replacement for Mercury 22-13563A3 and 22-13563Q3. Confirm the physical configuration and reference number before ordering.
Does this listing include the mating tank connector?
No. This listing includes one female fuel connector only. The compatible mating connector is listed separately as Sierra 18-8077-1.
