Sediment Bowl Assembly fits John Deere A AO AR B D G BO BR H 55 AA499R

Cast-iron sediment bowl built to the original spec for John Deere's letter-series tractors — the A, B, D, G, and H families that defined the line from the late 1920s through the early 1950s. The bowl sits ahead of the carburetor and traps water and sediment before they reach the needle and seat. Construction is cast iron with a brass handle and nut, matching the original. Inlet is 3/8" pipe, outlet is 1/4" pipe, with a 1/4-turn open / 1/4-turn closed action. Must be plumbed with a 3-way valve to function correctly.
