Morris Minor Owners Club

If you have an engine with a mechanical pump on the engine block instead of the electric one mounted alongside the battery tray, or if you were thinking of doing this conversion, the pumps are fairly easily obtained but the spacer blocks for between the pump and engine block can be a problem to source, but they are available from Mini Spares who have many Mini parts remade to original spec.
