Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance.
How do I know if it is compatible?
We recommend checking the SKU/MPN (22831T3) and Cross Reference list. If your original part number matches or uses the older bayonet twist-lock style, this is a guaranteed fit.
Will this fit modern 4-stroke engines?
Typically, no. This specific connector is designed for older "vintage" Mercury/Mariner systems and specific portable tank connections. Most modern Mercury engines use a push-click style connector.
