Radium Engineering Fuel Pump Check Valve Outlet Adapter M20B27 are engineered specifically for theInstallation Instructions This adapter is used to integrate a high flow check valve on the outlet of many fuel pumps. The valve outflows the integrated check valve that comes standard on many fuel pump outlets. Furthermore, decreasing this restriction allows the pump to operate at less current. This keeps fuel temperatures lower and prevents cavitation. The two billet aluminum adapter halves are secured together with a stainless steel retainer and
