Hi.
Yes the vacuum pump should have all hoses coming out conected to operate the egr (exhaust gas recirculation) valve and turbo waste gate.
Theres prob a good chance a that the missing hose worked to open the egr valve.
Not such a bad thing tho, No hose means no hot exhaust gases recirculated back through the air intake manifold.

Hi I have a Y61 with a TD42 engine, and the vacuum pump is leaking oil,can I just remove the pump and fit a new one? Is the pump gear driven or chain?

Thanks Richard
