A single fuel pump bracket with a 66mm inside diameter, dedicated to pumps with a 66mm body. Where a multi-size bracket trades a little precision for flexibility, a dedicated size gives the cleanest clamp around the pump and the tidiest installation. It carries the single-pump configuration, which suits the majority of road and club-level builds where one high-flow pump comfortably covers the fuel demand. Fit it to a solid mounting point rather than sheet metal that will drum, and use an isolating bush so pump vibration is damped rather than fed straight into the body panel. A secure pump mount is cheap insurance against fatigued fittings and split fuel lines further down the line.
