Abstract

A fuel storage or rail (12) in a fuel feed system of a piston engine comprising a body (20) defining a fuel space (21) for pressurised fuel, and at least one channel (22) that opens into the fuel space (21). At the orifice (25) of the channel (22) there is a trough-shaped recess (24, 24'), which extends only over a portion of the length of the fuel space (21).
