Yesterday, in a California SP campground, our Shurflo 4008 water pump pumped some air, then ceased pumping water while I was doing dishes, but continued to make noise.
Investigation showed that all 4 of the stainless steel screws that hold the pump body to the motor casting had vibrated loose and fallen out. I pulled the pump, reinstalled the screws, and reinstalled the pump and everything seems to be OK.
One screw had stripped part of the casting threads, so I had to remove one washer to get it to grab.
The way the casting is made, a person should be able to install longer screws, and jam nuts or lock nuts on the other side to keep this from happening.
