Anybody know what size fuel line I should use for a 70 hp 2-stroke?
3/8" is pretty standard. Be surprised if it was anything else.
3/8s most motor;s make sure you put the blub on in the right direction arrow to the motor
Make sure you buy USCG approved hose... nothing from the auto parts store.
5/16's for johnson's call your local marina service dept most can rattle it off for your engine.
Thanks for the informative responses. I'll either call a marina or just put a 3/8" on it. Currently it has a 1/4" & the motor won't run as fast as it did on old boat.
