I'm sure it is all about the money. As for why it would be is beyond me because the trucks and vehicles coming down the line already can handle it. The only difference it a sensor and the alcohol table in the ECM. Which is there on vehicles that didn't come with it like our Suburban. It had the table, just needed to be turned on. So why not just continue and give the public the option? There are so many out there that have the yellow cap and don't have a clue why and probably never will. I have talked to several while fueling up at our E85 source, Sheetz, and told them they can run it and they told me they didn't realize it. Yellow handle pump and yellow cap. At least here the E85 is a yellow handle pump.
