I purchased a replacement PSE/Central Locking pump for my 92 400se and was told the old PSE pump had been replaced by a new part number. See Pic's below. I would be greatly appreciative if someone could help clarify if the new part will in fact fit. Since the "hose module" will not fit on top of the new part, do I also need this new part too?

Thanks in advance for any help.
