Many people are not aware that bioethanol is not only used in E10, but also in "normal" super gasolines. Here is often to read in small print at the pump, which is included here up to 5% bioethanol. Many older vehicles are therefor not been set and it always comes often to disintegration of the fuel hoses. Also many tubes are not or only conditionally resistant against UV and ozone.
That was the reason for us to come now with an own product to market that meets all these requirements perfectly. Our fuel hose is now available in four standard sizes 5, 6, 8 and 9.3 mm internal diameter available.
