I have used ethanol enriched gas for over 15 years without problems, but decided to find out if this had any effect on the diaphrams in the fuel distributor when I recently had the unit rebuilt by a Bosch-authorized rebuilder. (The rebuild was a precaution because of sugar in the gas tank.) Their conclusion was that the distributor was unaffected by the ethanol. Then . . . I read Warren's post about the swelling of the fuel pump boot and recalled a recent experience where the outer boot would not fit over the fuel pump boot. I now suspect that the pump boot swelled as Warren suggested. However, I also feel that the best alternative is to continue using ethanol for the detergent, performance (higher octane) and environmental benefits and replace my existing boot (as one person suggested) with one that is reistant to ethanol/alcohol. We sometimes forget the number (dozens) of additives that are added to gas or diesel for that matter, and the reasons for going to alternatives to MTBE in particular based on the detrimental effects of MTBE on the groundwater. Also, where I live, ethanol is 10 cents a gallon less than the nonrenewable alternatives. Woody __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
