REFLECTOR: Franklin Fuel Pump

[Brian Michalk]

Are you running the diaphragm pump, or the newer rotary vane pump?

If it's the rotary pump, then that will need to be sent in for repair.

I machined an adapter for a sprint racing fuel pump for my airplane.  
The issue with adapting mine to anything stock, is you will need an 
external fuel pressure regulator.  I'm running 45PSI.
