Original BMW Power Steering Suction Hose, Reservoir to Pump, BMW 535i and 735i (1988–1993)

This Original BMW power steering hose is the suction line that carries fluid from the reservoir to the pump on the E34 535i and E32 735i with the M30 inline-six. A suction hose works on the low-pressure side of the system and feeds the pump the fluid it then pressurizes for the steering gear. BMW put this part number into production in November 1987 and gives its weight as 200 g. Each car uses one, and it is sold individually as a single hose. On the E34 535i, the application is limited to cars without self-levelling suspension.

Original BMW Parts carry a 24-month parts warranty.

BMW's English parts data lists this number under the name intake manifold, but physically it is the reservoir-to-pump hose described here and should not be mistaken for an engine intake part. One part number covers the M30 six-cylinder cars in both the E34 5 Series and the E32 7 Series, so the same hose serves an early 735i and a later 535i. BMW's data also shows the number on other M30 versions of these two chassis, while the fitment PMB supports covers the 535i and 735i.

Common Questions

Is this the high-pressure line from the pump?
No. It runs from the reservoir to the pump on the supply side of the system.

How many of these hoses does my car need?
