Match the correct model and revision
The 4138-111-E65 uses upper housing 94-800-23, drive 94-800-26 and motor 94-71-005-07. The 24V 4138-131-E65 uses a different motor number, 94-71-006-07. Neither is the 2 GPM 4128 motor and pump-head assembly.
This pump is documented for marine and general freshwater transfer. Confirm model suffix, 12V supply, 55 PSI shutoff and plumbing dimensions before choosing it for an RV system. The shared valve 94-800-01 does not mean the complete pump head is interchangeable with another family.
