Technical Background
These faults can result from the low-pressure fuel system operating outside its pressure tolerances. In the 3D
model, there is a clearance of approximately 19 mm (See Figure 1). It is possible for the component to vibrate over
time, which could lead to the fuel line to be damaged, causing a leak in the fuel line (See Figure 2).
