Modular Depot is proud to offer the best solution for upgrading the fuel line on the 03/04 Cobra. In independent testing (performed by Kenne Bell), it was shown that there was a 7 psi loss in fuel pressure from the pumps to the rail. By upgrading the fuel line and filter, this was reduced to 2 psi. The Ultra-Flo Complete kit comes assembled and ready to install. It includes:TJM Fabrication fuel line adapter (connects directly to the tank to adapt to -8 AN line)Earl's Performance Products Pro-Lite 350 Lightweight Fuel lineMagna Fuel 25 micro high flow fuel filterHigh Flow Fuel RailsComplete illustrated instructionsThe kit was designed to be as easy to install as possible. The fuel filter mounts in the factory location (with minor modifications). ATTENTION!!!!!!!!! All fuel rails will be blue anodized. Clear or Purple are available by special request. The below picture is an example of the blue rails, they are not the actual rails for the 2003-2004 Cobra. **Note: When ugrading to this type of fuel system, you may get a faint fuel odor when the car is stored in a closed area (garage).
