A fuel delivery system for an internal combustion engine, the system comprising a common rail fuel reservoir (2) having a primary rail axis (X-X) and comprising a plurality of outlets (5) at spaced locations along said rail axis (X-X) and a plurality of fuel injectors (10) arranged at spaced locations with respect to said rail axis. Each injector comprises an injector inlet (9), said plurality of fuel injectors (10) defining first and second groups (16a, 16b, 16c, 17a, 17b, 17c) of injectors. The system further comprises first and second groups of pipes (14, 15) of substantially equal length, wherein each of said first group of pipes (14) is of a first common design and connects the injector inlet (9) of one of said first group of fuel injectors (16a, 16b, 16c) to an outlet (5) displaced relative to said one of said first group of fuel injectors (16a, 16b, 16c) in a first direction substantially parallel to said rail axis (X-X), and each of said second group of pipes (15) is of a second common design and connects the injector inlet (9) of one of said second group of fuel injectors (17a, 17b, 17c) to an outlet (5) displaced relative to said one of said second group of fuel injectors (17a, 17b, 17c) in a second direction substantially parallel to said rail axis (X-X) and antiparallel to said first direction. Not more than one of said first group of injectors (16c) is disposed adjacent to said second group of injectors (17a, 17b, 17c). |
