I have twin 350 crusaders (GM) and duel 70 gal tanks current separated. Is it better to have them separated or to have a pipe or fuel line between the tanks to balance them. Currently my starboard engine burns 1 to 2 gallons more than the port engine.

"Interconnected, if it means a hose at the bottom of the tanks to force equal levels, is not approved by the safety agencies for gas. It's not even allowed to have a drain plug on the bottom. Any gas hoses below fuel level are a hazard. So, it goes: explosion, then sinking...

If "interconnection" means a valving arrangement to allow any engine to pull from either tank, then there are approved methods for doing so."
