Check Valve
A Check Valve must be installed at the tank end of the suction pipe on the top of the tank in a
serviceable location. Many clients install an extra check valve at the inlet to the pump. It is
important neither of the check valves interfere with the flow of fuel. They must be adequately
sized.
