This kit is designed for Minis before the pre-engaged starter was fitted. Hoses are specially made to have female BSP fittings. Stainless braided hose resists swelling and offers longest life. We also supply three (3) fittings in the kit for the block and the two (2) types of filter heads. You can leave the fittings in the engine when it is removed to prevent oil leaks and stripped threads.
