Cleaning our some of my spare fire truck parts.
I have a complete front mount Barton American UA50 pump. $200 for all. Complete includes everything that Barton American would have installed on a fire truck: pump, bumper mount, drive shaft, heat exchange, vacuum primer, carb regulator, water filter, heat exchange, all knobs, etc.
