To finish the hardware install, you will need to disconnect the oem fuel line connection at the firewall where the fuel line comes from under the car to the high-pressure fuel pump. Note, on a Mustang you will need a 3/8 inch fuel line disconnect tool, and for a Focus you will need a 5/16 inch fuel line disconnect tool.
6) Using the disconnect tool, pop the line apart and install the fuel line T fitting back onto the line then reconnect the OEM fuel line to the top of the T fitting. Note, be sure to make sure all fittings on the T are tight, including the 1/8 npt fitting on the back of the T.
7) Next, connect the provided line to the T fitting and the fuel rail. Make sure all fittings are tight, pressurize system by turning the key on, and check and address and leaks.
8) Wire up the Split-Second Controller (SSC) using the correct wiring diagram found in the FAQ section of our website.
Note, the SSC does not come with a 0 map loaded on it. If you plug in the port injectors before getting a base file from your tuner, the injectors will be firing at idle which will make the car extremely rich and undriveable. Always load a base map into the SSC before plugging in the port injectors.
