Just a thought, and curious if anybody has considered this before.
These days, cars all have evaporative emissions controls (aka "evap" systems). What this does is draw a vacuum on the fuel tank, then the ECM/PCM monitors the vacuum. If the vacuum decreases faster than a pre-determined rate, the check engine light will illuminate. This is to keep moisture (etc) out, and gasoline fumes in.
My thoughts... has anybody tried a sealed fuel system on a boat? It would be fairly easy to do, I would imagine. The engine provides the vacuum, a regulator could limit the vacuum (say 1-2 inHg), and you would drastically decrease the likelihood of water ever getting into the fuel. Be it splashing into vents on a rough trip, or condensation buiding inside the tank.
Any thoughts on this?
