Hey Marie! For a replacement I recommend the HydroMax RV Fresh Water Pump # P25201. This has the same flow as your old pump at 3 gallons per minute and a slightly higher pressure setting at 55 psi. A lot of people ask if the higher psi will cause damage so just an FYI that won't be an issue for your water lines or anything else.

Hey Marie, how did the HydroMax water pump work out as a replacement for your old Shurflo model? Your update could make it easier for the next person looking for a similar swap.
