I have 4 units that have the same problem with the coupler #5. I was wondering if you ever found someone that sold the coupler or got one manufactered??That is helpful. Its the motor end that is slipping. If its secured with set screws there is the possibility it can be repaired. We shall see soon enough.
The white coupler between the fuel pump and the motor is not turning. I took two of the pumps off and the square end on the white coupler is sheared off. The square part of the coupler slides into the motor. I assume the pump gets locked up or "gumed" up and the motor shears off the square end of the coupler.What issues are you seeing. It seems rare to have bought 4 units and all to have the same issue. Mine didn’t work either but I got it up going.
