Match the correct model and revision
The 4158 Supreme 12V motor is 94-71-000-17. The related 24V 4158-163 version uses motor 94-71-001-04, and the lower-output 4148 uses a different drive and complete head. The common valve and upper-housing numbers do not make these motors interchangeable.
This is primarily a marine/general freshwater-transfer pump; confirm the installed application and water-system ratings before selecting it for a custom RV installation. Use the full 4158-153-E75 label and the manufacturer table to find an exact repair kit.
