With in weeks of its introduction in the States (in particular our MV club area) we started having reports of fuel leaks, gas lines, and fuel pump diaphragms leaks and complete failures. Then later we started getting reports of plugged fuel filters and trash in carbs. Then came tank leaks on fuel tanks that had been sealed with the old yellow tank sealant. Dissolving the sealant also caused problems with plugged fuel filters. They introduced it over the winter and so when spring came the first parade everybody tanked up and the fun began.

So if they are introducing E10 in your area replace all the rubber fuel lines, do not use NOS parts, be sure that the replacement rubber parts actually rated for Ethanol. Do not buy cheap "rubber" fuel lines at the local auto parts, buy Gates or some other top line company.

I can post pictures of what this stuff does to MV fuel system parts I can post some.

They are now talking about let or making the gas companies in the US make E15 which will be even worse. US environmental agency doesn't even take into consideration vehicles made prior to 1990 even those they call legacy vehicles.

E10 goes bad in the carb within a few weeks, will last longer in the tank many MV drivers around here have gone to using marine grade fuel stabilizer.

Strangely the best way to avoid hard starting with CMPs is to drive them more and or replace the manual fuel pump with a electric pump. The electric pumps really help starting as they pump a small amount of fresh gas into the carb before you even try to start it.

Cheers and have fun Phil
