Thanks for the response. I've been checking online for a Shurflo that draws about the same amps as the original, and pumps about the same or more. The old one drew 4 amps and pumped 2.8 gpm. The Shurflo "Revolution" comes in two 12v
versions. One draws 7.5 amps and pumps 3 gpm. The other draws 5 amps and pumps 2.3 gpm. It seems like a pump that draws more amps would also pump proportionately more water, but the numbers don't seem to work out that way. I don't know how much amp draw the wiring in the trailer will handle, so I need to learn more about that too. I'll go with a new pump and start a new thread to clarify questions.
