Fuel Pump Flow/Pressure Tests
These tests will determine whether the fuel system can supply adequate volume of fuel at the desired pressure to operate the engine under full load conditions. The test is done at two points in the system (
fuel rail and
fuel pump) to isolate and identify the problem component; fuel pump, filter pressure regulator, or
fuel supply line.
