Swapping a K-series engine into your car? To set up the fuel system properly, you’ll need to remove the single inlet, return-less factory fuel rail and replace it with a dual port rail with return capability. K-Tuned offers a bolt-on fuel rail that has been specifically designed to set up the engine for a return fuel system. It is capable of supporting 700hp thanks to its large 12.5mm bore and 8AN inlet/outlet ports. It can be easily adapted for use with more common 6AN fuel systems by using some simple adapters, also available from K-Tuned. The rail is 100% compatible with aftermarket fittings from Earl’s and Russell to name a couple. This is the perfect rail for all K-series engine swaps.
