Hi everyone,

I hope someone can help.....I have a 1970-1971 Merc 7.5 Outboard, has the red stripe in the hood decals with the small style bayonet gas fitting on the motor. Unfortunately, I do not have the original fuel line for it or the original gas tank. I bought the fuel connector for the motor and the package recommends a 5/16" fuel line. That fuel connector does fit on the engine so I am good there.
I just want to be sure that a 5/16" fuel line will be OK or is I should be using a different size than that.
Thanks for your help,
Have a great day!
Ron

Yes 5/16" fuel hose will be more than good as the motor will not need more fuel flow than that. Put it together and enjoy.
