C250 TD- Cutting out on starting?

[JohnMcClane]

MY w202 is cutting out immediatelyy after starting in the morning. I replaced the clear lines and all the O rings about 2500 miles ago, had no issues up until now. Once it gets running again its fine for the rest of the day. Parking nose up or nose down seems to have little impact on it. Any ideas?

It does shout leaking clear line, have you checked for bubbles?

 

[JohnMcClane]

Yea, theres no sign of any bubbles! Its baffling.

leaking seals on the outlet side - clean the top of the pump where the hard pipes come out with a spray cleaner like carb cleaner, drive for a few days, is it now oily? if so it can be those seals, you need a special 33 spline socket to remove them.

Its most definitely the outlet seals then. Oily as anything on the two rearmost. Already got the socket, do you know what the part numbers are?
