<x-charset iso-8859-1>One thing that always concerned me with the nearly non existant fuel pump kits is the condition of the diapragms after all these years. Are they still supple and flexable? both layers there on the large one?? Good observations! I may be interested in a kit but Russ just sent me some new manf diaphragm material (which I havent opened yet :)) that Im going to attempt to rebuild mine with that but Ill let you know if I run into problems and you still have one avail.
