Doubt I'll find just the top, but the vac. pump on my mTDI was broken when I bought it from the salvage yard. The pump internals are find...its the connection going into the top of the vac. pump that was "snapped" off. I tapped out the old one and tried to install another from another TD pump i had around but it fits loosely and won't stay. I'm interested in just the top assembly, or possibly the entire unit. (or a fix for my situation). I've thought of just adding a barb fitting to the pump cover but am not convinced that it will solve the problem effectively.
