Re: Vintage Single OMC Line Fuel Tank

Hm.m.m.m, I should know the answer to that one since I just bought a new Attwood hose a few months ago. It had a big round connector. I’m totally unfamiliar with what that’s all about. Anyhoo, I cut it off and replaced it with a conventional OMC connector and all is fine.

You are correct, both of those pins must be pushed in. They are the fuel and air vent valves.
