Old Mercedes MFI Electric Fuel Pump Leaking or Stuck? Repair Kit Available

These early “short style” electric fuel pumps are very prone to leaking fuel because the rubber case o-ring seals harden with age. New pumps are no longer available and rebuilt are over $1000! If you risk buying a used one it will probably end up leaking or seeping fuel too. With the correct parts and instructions replacing the seals is something you can do yourself. Kent highly recommends you do this BEFORE the pump starts leaking. It will give you a chance to inspect the pumps internals, clean the impellter, clean the filter screen and make sure the motor is running properly. Don’t get stranded with a plugged filter screen or leaking fuel pump.
PLEASE NOTE: If the car has been sitting for a long period and the pump does not run, this kit MAY fix the problem. During periods of long storage the fuel gums up the pump drive vanes. Taking the lower section of the pump apart, cleaning out the varnish with carb cleaner, and installing this reseal kit will most likely solve the problem.
