    It is a combined unit, part pump & part fuel level sender. It, well, pumps fuel to the engine LOL. Not sure, but I guess on a diesel it will prime a 2nd high presssure pump in the engine bay? A faulty pump often comes up with a vcds scan, also manifesting in missing or poor power/slower acceleration.
