How to Remove Air from the Car Fuel System?
1 Answers
Methods to remove air from the car fuel system: Unscrew any air bleed bolt on the upper sides of the fuel injection pump several turns, manually pump the hand fuel pump until the discharged diesel flows continuously, smoothly, and without bubbles, making a hissing sound, then tighten the air bleed bolt and push the hand fuel pump back to its original position. If you're on the road and don't have the proper tools to open the air bleed bolt on the fuel injection pump, you can loosen any pipe joint between the diesel filter and the fuel injection pump, manually pump the hand fuel pump until the joint discharges a smooth, bubble-free flow of fuel, then continue pumping while tightening the joint.
