I have trial fitted the old fuel line on to the new fuel rail and it all fits up but when I ran the pump up to pressure a fair bit of fuel came out part way along the pipe so the arcing before obviously damaged the integrity of the pipe....it really was a lucky escape.

I have now removed the whol fuel line and sent it off to speedflow for a new one to be made up in their best quality pipe and I will get Fay to make up the line with all fittings on so I know it will be perfect. If I can get it back this week I can finish it at the weekend and then take the car for a fresh mot and go have some fun.
