ZEX™ Blackout Nitrous System™ Fuel Rail Adapter Kit For Ford

Q: Are fuel rails sold individually?
A: Fuel rails are sold individually unless otherwise noted.

Q: How do you install fuel rails?
A: Fuel rails are installed by removing the injectors and fuel pressure regulator from your factory rail. The factory fuel rail is then removed and the new unit is installed in its place. Specialty tools are needed to remove the fittings on your standard rail and to install new fittings into the new fuel rail. This job should be left to the pros if you've never done a fuel rail before.

Q: What do fuel rails do? Why buy fuel rails?
A: Fuel rails are designed to keep pressurized fuel flowing to the injectors. When high performance motors are built and the fuel pressure is increased, sometimes the standard bore on the fuel rail is too small, restricting fuel flow to the injectors and causing your car to lean out.
