A fuel distributor features a pressure accumulator 2 with a longitudinal hollow space 3 to receive pressurized fuel. The pressure accumulator 2 possesses at least one threaded socket 7 which connects with the longitudinal hollow space 3 and which features interior threading 8, and into which a threading cap 11 with exterior threading 13 is inserted. The threading socket 7 features a sealing surface 16, which ends up being pressed onto a sealing seat 18 set up inside the pressure accumulator 2. According to the invention, a leakage channel 27 is formed within the threading cap 11. The configuration of the fuel distributor according to the invention with the leakage channel 27 in the threading socket 7 allows leakage testing under high pressure to be carried out during a short cycle or detection times, and with a high degree of precision.
A fuel distributor, which features a pressure accumulator with a longitudinal hollow space to receive pressurized fuel, where the pressure accumulator possesses at least one threading socket featuring interior threading connected to the longitudinal hollow space, and where a threading cap is inserted into the threading socket, which itself features external threading, where the threading cap features a sealing surface, which ends up being pressed onto a sealing seat set up in the pressure accumulator, wherein the threading cap has a leakage channel formed by a cross bore in a cylindrical section which is connected to a recess.
