Questions & Answers

Is this a genuine original part?

Yes, this is an authentic Tohatsu OEM replacement part, supplied in original factory packaging where possible.

How do I know if it is compatible?

This seal is designed exclusively for the "built-in" (integral) fuel tanks found on the 2.5hp and 3.5hp 2-stroke models. If your engine is a 4-stroke (MFS series), this part is not suitable.

Will this stop fuel from leaking into the engine tray?

If your current seal has perished or hardened, fuel can seep out from the tank neck area. Replacing it with this fresh rubber seal will restore the required vapour-tight closure.

Note: Please verify your original part number or engine model against the fitment list above. For support, please contact 4boats.co.uk.
