ABSTRACT:
The service life of a filter utilized for the purification of fuel oil drawn from a storage vessel for transfer to a burner nozzle is increased by providing a holding tank, positioned between said filter and said nozzle, which permits the recycling of already filtered fuel oil. A float valve in said holding tank facilitates controlled delivery of fuel to said burner nozzle, and regulates the amount of fresh fuel drawn from the storage vessel.
