Fuel Volume Specifications
9. To determine the correct fuel volume, refer to Fuel Volume Specification. To use the chart, refer to the following procedure:
^
Draw a straight vertical line at the measured RPM.
^
Draw a straight horizontal line at the measured fuel volume.
^
If these two lines intersect below the flow line, this indicates a defective transfer pump or a line restriction.
^
If these two lines intersect above the flow line, this indicates acceptable fuel flow.
