We worried a little bit over plumbing up the fuel system to a fuel-injected motor, but it turned out not to be too tough. Fuel injection systems are different from carbureted motors because they require a lot of fuel pressure at the fuel rails, and most require a return line to circulate unused fuel back to the tank. The key to getting things to work for us was this In-Line Universal Electric Fuel Pump from Holley (just behind the fuel cell). This pump can handle more than 600 horsepower and provides plenty of pressure, plus it was a snap to hook up. All it requires is a power wire (that cuts off when the ignition is off so the pump won't drain your battery) and a ground. Make sure to plumb everything with high-pressure fuel line--we learned the hard way that standard line will split in a hurry and spray fuel everywhere. The blue stuff and the steel braided line is high pressure. The black line you see in this photo is just a vent for the cell. To get the fuel to the motor we simply connected the line from the pump into the stock fuel lines that connected to the original fuel tank. The entire fuel system turned out to be hassle-free all through the race weekend.
