What is the main benefit of the 1/2-inch fuel bore?

The larger 1/2-inch bore allows the fuel rail to support higher fuel flow rates needed for engines making up to 1,000 horsepower. It also helps to reduce backpressure pulses created by larger fuel injectors.

Can I use this fuel rail with my stock fuel injectors?

Yes, this fuel rail is designed to work with stock injector sizes as well as larger aftermarket injectors. The larger bore helps dampen pressure pulses regardless of injector size.

What is the 1/8th NPT port for?

The extra 1/8th NPT port on the fuel rail is a threaded opening. You can use it to install a fuel pressure gauge to monitor your fuel system's performance or to connect a nitrous oxide system.
