Arrow Fuel Pumps
Anyone fly an Arrow III? Had any problem with the electric fuel pump? Ours has had NINE pump failures in three years (and about five new pumps, the rest being "repaired").
Latest explanation was "fuel contamination" that took out the mechanical part of the pump. Other failures have been with the electric motor as well as the pump half.
We've had all the wiring (from bus bar/circuit breaker, via switch, filter, right to the pump changed. That didn't fix it.
Should there be a "return line" for high-pressure fuel back to the tank? We don't have one...
