I OWN A 2003 BMW Z4 AND HAVE HAD TWO FUEL PUMPS AND FILTER REPLACEMENTS. THE CAR HAS APPROXIMATELY 21,500 MILES. THE FIRST FAILURE WAS JUNE 2008. THE SECOND FAILURE OCCURRED WITHIN 1,000 MILES OF THE FIRST REPLACEMENT. BMW DEALER MAINTAINS IT IS ETHANOL IN THE PREMIUM GAS I BUY, WHICH IS FROM CHERVRON. THE FUEL PUMP IS SUPPOSEDLY SUBJECT TO FAILURE IF THE ETHANOL CONTENT EXCEEDS 10% OR MORE. I HAD THE CHEVRON FUEL TESTED AND IT FALLS WITHIN THE 10% LIMIT. ALL FUELS IN THE PACIFIC NORTHWEST CONTAIN UP TO 10% ETHANOL. I FIND IT HARD TO BELIEVE THAT BMW CANNOT DESIGN A FUEL PUMP TO HANDLE THE FUELS SOLD IN THE U.S. I SUPECT THE FUEL PUMP DESIGN IS FAULTY. ANYWAY I AM OUT ABOUT $2000 AND I AM AFRAID TO DRIVE THE CAR VERY FAR FROM TOWN. *TR
