To check the fuel flow in a Mazda RX-7, first ensure safety by relieving fuel pressure using the Schrader valve on the fuel rail. Then, disconnect the fuel line from the rail and direct it into a container. Turn the ignition to the "On" position (without starting the engine) to activate the fuel pump, and measure the amount of fuel collected in a set time (e.g., 30 seconds). Compare the flow rate to the manufacturer's specifications to determine if the fuel pump is functioning properly.

A fuel return line should flow freely back to the tank. There may be a check valve on the fuel return line that prevents backflow from the tank to the regulator.
