Information on use
The tank indicator is incorrect or doesn't move? Was the pump module installed incorrectly? And why are there markings on the tank and on the cover?
Potential complaints:
• Tank indicator shows incorrect values
• Tank indicator remains stuck at a certain value
• Tank indicator shows incorrect values
• Tank indicator remains stuck at a certain value
The shape of modern fuel tanks is optimised to make the most use of the available design space (Fig. 1).
In order to fulfi l legal requirements for tank leak-tightness, more and more components, such as pressure regulators, are now located in the fuel tank itself (Fig. 2).
If the fuel delivery module is incorrectly installed in the fuel tank, the fl uid level sensor may get caught on these installed components (Fig. 3). Consequence: the tank indicator remains constant despite the decreasing fuel level.
