what does this manifold collector look like ? following the small leak off pipes from the injectors they go to a metal block. pulled this pipe off with engine running and fiuel sprayed from the block (got covered in fuel....... nice..) fuel seems to be leaking from the pump, small black cycinder on the end, with a wire coming out ? what this part called then ?
