Motor vehicle fuel tank with reserve tank has suction unit drawing in fuel from filter at low point away from reserve tank

摘要

The fuel tank (1) is fitted with a reserve tank (4) and incorporates a suction unit in the form of a jet pump (19), drawing in fuel directly from a filter (7) at a low point outside the reserve tank, and delivering it to the reserve tank at a higher point above the reserve tank's minimum desired level and above the suction point. The reserve tank has a wall with an aperture at the top linking it to the main tank, and the suction unit delivers fuel to it through the aperture.
