System Inspection

■ Check the fuel filter for blockage

Remove the fuel pump and check filter debris and clogging of the fuel supply line.

■ Check the fuel level

If you run out of fuel significantly on ramp, it may be a factor of degradation of the fuel pressure.

■ Check low-pressure fuel supply line leakage and blockage.

Low-pressure fuel supply line damage and blockage can be a factor of the fuel pressure drop.
