Match the correct model and revision
The 4148 Premium has drive 94-801-02 and full pump head 94-801-11. The similar-sized 4158 Supreme 5 GPM unit uses 94-801-12 and 94-801-13 instead. Check the complete model number before selecting an internal repair kit.
The manufacturer's application is marine and general freshwater transfer. If using this unit in a custom RV installation, confirm wiring, 55 PSI shut-off, the 4 GPM requirement and pump port compatibility. A 24V 4148-163 variant uses a different motor.
