Yep, mine failed in a national forest campground in the mountains of Northern New Mexico about four years ago. I was incredibly lucky that a small auto parts store in a small village several miles down the road carried a few rv parts. They had one, dusty pump on the bottom shelf that probably had been there for years. I bought it and installed it and saved our trip and saved driving a long way to a larger town. I kept the old pump and rebuilt it when I got home and carry it for a spare. I had to do a bigger modification to fix it than I could do out in the middle of no where. The pump I bought was slightly lower in gpm discharge than the old one but not enough to noticeably change it out by buying a larger pump.
