AC fuel pump diaphragms

[andrew honychurch]

I am just refurbishing my AC fuel pump and even though its new, the diaphragm is not going to work for very long from past experiences of these items. Modern fuels with ethanol tends to dissolve the old material. I wonder if anyone has dealt with this problem other than by putting in an electric fuel pump. Is there anyone out there making new diaphragms? Given the tendency for Carriers to suffer with fuel vaporisation maybe an electric pump will be the best way forward. Any thoughts much appreciated.
