    摘要： A fuel rail for a fuel injection system is disclosed. The fuel rail includes a first portion including a generally elongated base, at least one mounting bracket and a plurality of fuel cup openings in the generally elongated base. The fuel rail also comprises a second, generally U-shaped, portion having a first and second opposing sides. Each of the first and second opposing sides are sealingly connected to the generally elongated base with a laser weld. The second portion also has a supply end having a fuel supply opening, and a closed end, distal from the supply end. The closed end and the supply end are sealingly connected to the generally elongated base with a laser weld. A method of manufacturing the fuel rail is also disclosed.
