ABSTRACT:
A fuel distributor pipe for supplying fuel to two cylinder banks of a V-shaped engine comprises main pipes of metal construction which are respectively fixed substantially horizontally with respect to the cylinder banks, and a sub-pipe of metal construction which connects the main pipes. The sub-pipe comprises three curved portions in a vertical plane comprising two convex portions and one concave portion situated therebetween. When there is an error in the vertical direction of the position of connecting parts between the sub-pipe and main pipes, these curved portions disperse the stress due to the error, and concentration of stress in the connecting parts is avoided.
