Enderle quick release fuel pump mount. Made from billet alum. and anodized black. This is the new design using two quarter inch bolts as the earlier had one and didn't provide quite enough clamping.
This mount fits the 110, 600, 760, 990, 1100, 1200 series pumps and allows the racer to clamp the fuel pump on without using a wafer bolted to the fuel pump.
