I'm going for the repair approach rather than catch tank.
Found the split part, 06A 103 213 AK, and almost fell off my seat when I found out its £50!!!
Wasnt paying that, so I brought 0.5m of pipe from a boat chandler. Only issue is that the internal bore is quite a bit smaller than the broken part, is that important ?
It's a 210 bhp AMK engine, and the pipes aren't the same as on the guide, why is this ?
Also snapped the dip stick, with part of it getting stuck inside the tube from block!
