Rusty Coolant Pipe on early models like e12
 

Hi, what do people do to replace the coolant pipe under the inlet manifold ?
Is there a source for replacement, or are others making or using an alternative (hose and Tee's or modify hoses from later M30's) ? thanks

PS here are two of mine, both rusty

That part is long NLA, My guess is that youd have to have one fabricated which doesn't look to be too complex. I had to have an intake elbow made a few years ago with a similar number of bends, tabs, and bungs and the whole project cost me around $150. YMMV, good luck.
