I have a 5-gallon Harwood foam-filled fuel cell, 2 Mallory Series 140 fuel pumps, 2 Mallory returnless fuel pressure regulators, and a Mallory Series 140 filter for sale. This setup came off a Camaro drag car, and fed a Holley Dominator running gasoline. I turned the Camaro back into a street car; all of this was working when removed earlier this year. The pumps and regulators are heavy-duty for serious racing, and are rebuildable.
For reference, Summit prices the pumps are $301 each, the filter at $143, the regulators at $139 each, and the fuel cell at $130, for a total cost of $1,153.- not including the valves, gauges, fuel cell mount, etc.
