A friend had a head that the handle/pump holder broke. They were in a remote location and were unable to have one shipped to them.
I did some cad work and came up with this model.
When printing please use a strong infill. I would recommend 40 - 50%
Another option would be to fill the part with epoxy and let it dry before installing.
This part will also need support.
