Glenn Lenhart of Glenn's MGs in Tampa, Fla. (one of the best British sports car shops around), warns, "We are starting to have ethanol gas problems here."
According to Lenhart, there's been a rash of sticky fuel pump valves and sticky carburetor inlet valves. One old car had a few gallons of old fuel in the tank when Ethanol fuel was added and that caused the new gas to "Act like glue," says Glenn.
"If you have to use ethanol, the tank must be drained of the old style BMTE fuel," Glenn warns. "I am still researching the problem and most of the good information is coming from the boating industry."
Glenn says that all cars serviced at his shop will now be having fuel injection hoses installed anywhere that there is an old style rubber hose. He will also put a gas additive into each car. Supposedly, it will keep E10 ethonol fuel fresh for up to a year.
