Thanks to everyones help I think I’ve worked out how the fuel lines are clamped at the front and after buying another set I’ve eventually managed to bend them to fit. I do have to say that it did prove quite difficult as they are very hard to bend, particularly the feed line. Anyway, all in place now except for the fact that I do seem to have a lot of return pipe feeding into the engine bay and wonder if someone knows how this should run.
