This is way different from the A/C glass bowl. The entire top is much larger in diameter than the glass top and flat. The inlet and outlet stick up from the flat top of the pump like a 3/4 bolt head about an inch tall . The threads for the fuel line fittings are on 1 of the flats. The entire top is brass colored and has almost a flange that covers the base of the pump. The top rotated to line up the fittings.
