3587-1 Buffer gas tank

Keeping your fuel tanks properly isolated from vibration is crucial for longevity and paint protection. This Colony gas tank buffer is a precise reproduction of the original 3505-36 part used on 1936 to 1947 Big Twin Knuckleheads and 1937 to 1948 U model Flatheads. Over time, original buffers perish or go missing, leading to metal-on-metal contact that can damage expensive vintage tanks. By installing this period-correct reproduction, you ensure your tanks are mounted as the factory intended. It is a small but vital component for anyone performing a ground-up restoration or routine maintenance on these iconic pre-war and early post-war machines, helping to preserve the integrity of your classic fuel system.
