Anybody know the fuel hose ID typically used on this engine? Want to order some to have on hand for next trip, but not near the boat. Thinking it might be time to replace it all.

Anybody know the lengths involved?

Anybody ever use an electric fuel pump and a couple of 3 way valve to make their own mini-fuel polishing system? Isn't there a return line from the engine to the tank? If I put in a couple 3-ways, one between my filter/electric pump and then break into the return line, then theoretically I would think I could polish my fuel myself (obviously when the engine is not running) What do you think?

I am thinking 5/16 id on the fuel tank and 1/4 on the lift pump to the small filter going to the injector pump
