My boat engines have a number of aluminum assemblies in the fuel system. They were anodized when new but the ethanol in the gas here in CT has eroded much of the anodizing away. The exposed aluminum corrodes and plugs the injectors. I would like to have the parts either re-anodized, chrome plated, or whatever to avoid the corrosion and subsequent plugging of the injectors. This part of the fuel system is downstream of the filters and as it's the high pressure circuit for the injectors, another filter cannot be added. Any ideas as to the best method of protecting these aluminum parts for the ethanol gas would be greatly appreciated.
