Fresh Water Boat Pump by Shurflow, Self-Priming 12 V, needs new diaphragm - can be rebuilt with new diaphragm.
Sureflo Aqua King Premium 4.0

The diaphragm only needs to be replaced and should be easy to rebuild.
Sold as-is. Worked great.
We decided to just invest in a new one, so this repair project can be a great find for a DIYer. (New pumps are $200-$335.)
