Well Rick I hate to be the bearer of sad news; but you have it figured out. That is just one more tactic the feds intend to use to get rid of older vehicles.
Ethanol is hard on rubber and composite components, diaphram materials, (even the modern types), and some types of metals as well used in older carbs, fuel pumps, etc. Top end current production car and truck manufacturer's are having a time trying to keep up with changes in an attempt to stay compatible with today's fuels. Even some so called flex fuel compatible vehicles have had and continue to have issues because of the stronger ethanol blends that keep coming. I wish, but it simply is not profitable for suppliers of parts for most older vehicles to tool up and attempt to produce 100% compatible components. As we all should know, if it ain't profitable for suppliers, it ain't happening; they simply can't afford to produce items that will never make a profit because of small sales markets.
Older diesels are suffering as well, mechanical injection pumps and injectors are fairing rough since the forced ultra low sulfur diesel fuels are the norm. This applies especially to the rotary distributor type of injection pumps. Some relief for them comes in fuel supplements that can be added to fuel to restore lubricity needed for the older components; but from what I've seen over several years, that isn't as good as the older diesel fuel blends were before low sulfur came along. Even with the brand new Cummins electronic engines we install, it isn't manditory, however they (Cummins) suggest using a lubricity additve in the fuel. They supply fuel filters with the engines that have slow released lubricity additives incorporated into the spin-on filter elements. Fuel system warranty is void if the filters aren't serviced on a strict schedule or if any other type filters are used as replacement.
