Abstract
A level sensor and fuel pump assembly insertable through an access hole of a fuel tank so that an elongated fuel pump is disposed substantially completely within the fuel tank, and so that a flange of the assembly covers the hole and is engaged sealably to the wall of the fuel tank. The fuel level sensor has an arm which projects generally laterally when in a biased operating position from the elongated fuel pump to a float at a distal end. During insertion of the fully pre-assembled fuel sensor and pump assembly through the access hole of the fuel tank, the fuel level sensor is pivoted from the biased operating position to a collapsed position by an external force thus pivoting the fuel level sensor generally parallel, and closely orientated, to the fuel pump. This temporary orientation permits insertion of the fuel pump assembly through the relatively small access hole of the tank. After insertion, the external force is released and the fuel level sensor pivots from the collapsed position back to the operating position.
