Hi Trevor
yes I had thought about that, and wonder in practius if it would make any real difference depending on what frequency it was set to as the spring does the pump and the pulse just returns the plunger, I may do a test anyway,
the other option is similar to your prox sensor, I would use a hall effect to pick up where the plunger was and triger the coil ( a soild state switch with histereasis) however you spell that word
what are they like to seal? as fuel must be present round the coil, or is mine missing something?
