Questions & Answers

Is this a genuine original part?

How do I know if it is compatible?

We recommend checking the SKU/MPN list above. This tank is specific to 2-stroke models and will not fit the MFS 4-stroke versions of these outboards.

Does it include the fuel cock/tap?

This listing includes the tank and the cap assembly only. The fuel cock (tap) is typically sold separately or can be transferred from your existing tank.
