I need to replace the leaking water pump in my '88 260e.

Fastlane indicates that the early M103's require a 103 200 14 52 drain return line and 124 501 33 32 lower radiator hose. Does this mean the replacement water pump will not fit with the original parts?

Anyone know if the replacment pump is a direct fit or if updating is required? I'm willing to go to the dealer if need be for a direct fit.

Thanks,

John
