Picked up a beater 420SEL because I like to punish myself. Noticed there were some pumps or motors behind the right rear axle. Seem to make intermittent noise even with the key off. Any clue as to what this/these are? Car was sitting for a while and is definitely a project. But she does fire right up. I'll try to take some pictures soon.

Fuel pumps. There is a center locking pump in the trunk next to spare tyre which also makes noise when doors are locked or opened.
