This replacement kit is engineered as an original-equipment match for the 510026 axial cam pump and ships with the fittings and hardware needed for a straightforward swap. The kit’s cast aluminum manifold includes a 3\/4\" garden-hose low-pressure inlet, an M22 high-pressure outlet, an integrated unloader, thermal relief valve (TRV), installed valves, and a soap hose screen for reliable performance.\u003c\/p\u003e\n\n\u003ch3\u003eWhat parts are included and why does that matter?\u003c\/h3\u003e\n\u003cp\u003eThe 7113810 kit arrives ready to install with the key components preassembled so you don’t have to source extra parts.
