Yea, someone broke the drain plug on mine and glued it back on for athsetic purposes :|
I got the pipes off the head unit, with some stilsons, but apparently no one sells the pipe fixtures I need to put it all back together so i ran a new pipe in from the tank to the lift pump on my 200TDI.
If you are just bipassing it though, you should be able just to cut the pipe and put a section of larger pipe over the top of the joint and put the jubilee clips at either side of the joint you have put in....if that makes sence.
