Fuelhose that connect left and right injectors moved from rear to front of manifold. Now with a 15mm fire sleeve around. Fuel line from filter and returnline connected to manifolds, also with firesleeve. A limited space between engine block and exhaust downpipes made this to a challange. Oil returnline also with fire sleeve 20mm, connected to engine block, and oil-container. Than rear downpipe and left muffler was reinstalled.
