Hi Dad of 2

You may have the Classic Shurflo pump. Some times there is a pump number on the motor area.
And here is another link if yours is the Classic

And here is a cut sheet on it

There are also links on that page to an exploded view. You can buy the entire diaphragm assembly less the motor. I do not believe they sell the small minor parts, just large pieces in a sub assembly.
And here is a personal recommendation. Once you rebuild the pump or buy a new one, install an inline strainer. Dirt is the biggest enemy of these pumps. Once the internal check valves no longer seat, it is sit and spin time and no water pumping.

Here is one place I have purchased from with positive experiences. Just not a water pump, brakes etc. They have the entire pump, or the entire head and the strainers.

If you do buy a new head or pump, I would flush the tank out before hooking up the new pump. If you know there is some dirt in the tank that can do your new pump in quick.
Good luck.

PS That is the basic water pump that many/most new campers come with. There are better pumps with more features however if you are after the simplest one that does pump, the Classic is the basic pump. Shurflo and FloJet both offer many other models with more features yet some how the water pump generally never ends up on the options list for upgrading when buying a new camper. However the aftermarket business offers many kinds. When mine went out I upgraded to a Flo jet variable speed pump. Mine died from sucking and air bubble when the tank only had 1” water left in it and ran for hours on end dry. Never worked right after that. When you leave the camper, turn off the pump. Lesson learned. Mine was less then 1 year old when it died.
