How to check before ordering: the part number on your old part should be 309-70036-0 (or a superseding number). If you are not sure, send us your engine model and serial number (on the plate on the engine bracket) and we will confirm fitment before you order.

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 for the "built-in" (integral) fuel tanks of the Tohatsu M2.5 and M3.5 (2.5 and 3.5 HP 2-stroke). To be sure, check the part number 309-70036-0 or send us your engine model and serial number.
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.
