I removed my high pressure fuel pump to replace the cam follower on my 2006 2.0. When I took it off, something fell and I can't find it. I believe it was one of the O rings that sits inside the fuel inlet ports, but I'm not 100% sure. I also need the 8mm triple square bolt that goes in there as mine is stripped. Does anyone know where I can find a break out diagram of the fuel pump so I can find what I am missing. Also does anyone know where I can buy just the parts so I don't have to replace the whole fuel pump?
