It was pooring out all around the bottom of the pump I could not see any obvious split when I took the pump off. I guess the pump was having issues since I got the car because now I have replaced the thing it going up hills like stink, even accelerated in 5th up hills with a 1.2 transfer box on. The engine is a 200tdi. Oddly even with a leak, and not as bad as in the video, it was still doing 34mpg on a run, I think this will drop now though because today I have been tearing around like a luney in it. But I will say every little thing I have replaced to do with the fuel system over the past 18 months has made a difference so I'm chuffed at this one, just need to do the filler cap air feed now.
