Just curious if anyone on the list has installed one of these? You know, the kind with the large spin off filter (looks like an oil filter) and mounts in the bilge area with the fuel hose connecting from the tank to the filter and then to the main engine. I'm debating whether to install one given the lack of anything but E10 around my neck of the woods. Also, hearing bad things about E12 or E15 working its way through the EPA approval process with the biofuels interests pushing this through rulemaking.
