I'm in the process of wiring up a 3 bank battery charger and I'm wondering if there is some code that states that I have to be away from any fuel lines a certain distance with my AC wire. My AC wire runs down to the rear of the boat from inside the gunnel and I want to run it into the engine compartment and follow the back wall of the bench seat to where the charger will be mounted in the engine compartment. In the gunnel there is the main fuel hose that goes from the filler to the tank and in the engine compartment there are fuel lines that run along this same wall that go to each engine.
