ABSTRACT:
An electrically heated fuel pick-up assembly insertable into a motor vehicle fuel tank for defrosting and dewaxing the fuel therein at the fuel pick-up point includes an inner tube substantially coextensive with and disposed within an outer tube in spaced relationship thereto to define therewith a fuel flow passage therebetween. The inner and outer tubes are immersed within the fuel tank and are supported by a base member attached to one end of the outer tube. A flexible PTC resistance strip heater of the type which automatically adjusts its heat output in response to fuel temperature is spirally disposed along the entire length of the passage on ribs secured to the inner tube for heating the fuel flowing through the passage from a fuel inlet in the end of the inner tube opposite the base member to a fuel outelt in the cap member communicating with an engine fuel supply line.
