Abstract
A fuel sending unit assembly includes a pump for pumping fuel from a storage system to a combustion system, a float for measuring the level of fuel remaining in the storage system, and a filter for preventing debris contained in the fuel from entering the combustion system. The assembly is characterized by the filter being attached to the float. In this manner, the assembly intakes fuel from the fuel surface rather than debris or liquid contaminants which have settled on the bottom of the tank. In a preferred embodiment, the assembly further includes a tube for attaching the float to the pump and for channeling fuel from the filter to the pump.
