ASS Servo oil tank BMW E36 (M50) Aluminum container for servo oil with buffer plate. Replace your constantly leaking original container with this one! The container is developed for E36 with M50 and ASS engine mounts but also fits original engine mounts and other models. It is only necessary to shorten the original hoses a bit and change the direction slightly on the banjo connection on the servo pump to get the ultimate solution! The connections in the bottom both have G 1/2 threads and can easily be replaced with e.g. AN-fittings. Hose nipple suction line : Ø16,5mm. Hose nipple return line : Ø12,5mm.
