Inspect the transfer pump lower for wear or fatigue.
- Worn seals can cause pump to run excessively fast and/or not generate the desired supply pressure.
- A broken top pin in the pump lower will cause the pump to easily move in both directions without generating pressure
- A broken bottom pin will cause the pump to only generate pressure while moving down. The pump will easily move upward while not generating pressure
