Beschreibung
Zusammenfassung:	According to a first aspect the invention regards a fuel rail (1), comprising a main gallery (2) and in particular at least one fixing bracket (3) and in particular at least one injector cup (4). In order to provide an improved fuel rail (1), the invention suggests that the fuel rail (1) is a one-piece fuel rail (1) which comprises at least one first fuel rail section (5) having a first average density and at least one second fuel rail section (6) having a second average density, wherein the second average density is smaller than the first average density. According to a second aspect the invention regards a fixing bracket (3), in particular for a fuel rail (1), wherein the fixing bracket (3) comprises a body (7), which in particular has a cylindrical shape, said body (7) extending around a hollow cavity (8) and along a longitudinal direction (9) of the hollow cavity (8). In order to provide an improved fixing bracket (3) the invention suggests that the body (7) is a one-piece body (7) which comprises at least one first body section (17) having a first average density and at least one second body section (18) having a second average density, wherein the second average density is smaller than the first average density. According to a third aspect the invention regards a fuel rail (1) comprising a main gallery (2) and at least one fixing bracket (3) as described before. According to a fourth and a fifth aspect the invention regards a method for manufacturing a fuel rail (1) and a method for manufacturing a fixing bracket (3).
