When a Model 4008 pump starts losing pressure or won't prime right, a worn valve assembly is often the culprit, and this Shurflo part gives you a way to repair rather than replace the whole unit.
It's built to match the exact fit of the original component, with barbed connections on both the inlet and outlet for a secure hose connection.
Double-check your pump's model and part numbers before ordering to make sure this matches your specific unit.
