Hello, my name is Mike, I am the machinist at Then And Now Automotive in Weymouth, MA. I gave up on lurking and decided to join the board.

Mike, obviously your company is best known for it's fuel pump rebuilding service. Why don't you tell us about the challenges you've had with modern fuels eating fuel pump diaphragms, and how your company has finally hopefully found a diaphragm material that is impervious to even E-15 fuels.

The material we use, and have used for many years is Buna-n Nitrile. We have found that it is one of the only two materials that will stand up to any amount of alcohol that is available today. I personally have tested it in 100% alcohol for over 30 days and found no problems with the sample. The valve plates are made out of Viton, which is another material that seems to be impervious to this fuel.

I only have a late model vehicle now, in 2009 I cleaned house and unloaded the last of my toys, all except the motorhome.
