Okay everybody I'm doing a project on an obs. I'm wanting to upgrade to 3/8 fuel line and keep both my tanks functioning. I don't want to sump them together. has anybody ever found or used a aftermarket tank selector valve with 3/8 ports? Or anything anybody has ever done to achieve this keeping their dual tanks? Also thought of running dual electric pumps with external relays using the power wires from the original selector valve to switch pumps and tanks. I appreciate any advice and opinions.
