Hi there, just swapper over the high pressure fuel pump on my c220 cdi, with a genuine replacement Bosch spare. The part that came out was a cn2 and its replacement a cn3 . The car is refusing to start, I can see air bubbles rising Ito the small pump and air in the lines back to the filter. I did not fill the pump as there was no obvious filling point, only by submersing the whole pump can it be filled I guess and I haven't done that. Any advice would be greatly appreciated as I have been told its self bleeding but haven't had any joy
