ACCEL/DFI takes the fuel rail to a new level with it's introduction of the 'Race' Rail. This all-new design incorporates a enormous 0.625" internal diameter to fuel the most demanding applications. The smoothly contoured outside dimension is actually smaller than our previous design, which allows for increased clearance with linkage or cable assemblies. The entry area is large enough to accept a threaded -8 fitting. Ideal for gasoline or alcohol applications. Available in lengths ranging from 1' to 6'.
