Fuel pumps should be positioned at or below the height of the sump. The drawback of running a stock tank instead of a trunk-mounted cell is that it requires dropping the pump down closer to the ground. To accomplish this, Buck mounted the pump on a custom bracket made of 1/8-inch steel plate, which was first welded to the Mustang's framerail. To prevent gunk from ruining the fuel pump's internals, Russell recommends installing the filter between the tank and the pump. The pump's compact size allowed us to position it parallel to the side of the car, and connect the filter directly to it at a 90-degree angle.
