The Tegiwa Fuel Dump Churn dry break ripper cap.
This is a spare cap or maybe an upgrade for your churn without a dry break cap. This is essential for many endurance race series and the air vents through the fuel as specified by the MSA for refuelling in the likes of the 750mc Club Enduro Championship.
This allows the whole 20 litres to empty in 45 seconds.
