GALVANIC CORROSION IN 4-TEC FUEL TANKS

I had a problem which I think is galvanic corrosion of electrical terminals inside the fuel tank. As ethanol increases conductivity of gasoline from a dielectric/insulator to a conductor is allows for galvanic erosion of anode connectors.
Ethanol also increase gasolines potential for absorption of water thus further increasing corrosion and galvanic erosion.

I have had 2 fuel pump failures due to erosion of positive terminal crimps connecting the 12volt supply to the pump within the tank... Its and expensive business and a design problem now ethanol is being added to fuel in greater concentration without being labelled as including this conductive and corrosive additive.

The latest pump has failed with only 2 hour of use and 3 months submerged in a full tank of gas. Luckily Seadoo changed the second pump as a warranty part replacement but they should look into a redesign of the fuel pump installation inside the tank.
