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

The larger 1/2-inch bore in this fuel rail supports higher fuel flow for engines up to 1,000 horsepower. It also helps to dampen backpressure pulses, which can be created by larger fuel injectors.

Can I install a fuel pressure gauge with this rail?

Yes, this fuel rail includes an additional 1/8th NPT port specifically for installing a fuel pressure gauge or a nitrous system.

Does this fuel rail come with all the necessary hardware for installation?

The fuel rail includes a custom fitting for the factory fuel line and is pre-tapped for -6 AN or 9/16"x18 fittings. You will need to source any additional fittings or hardware required for your specific setup, such as a fuel pressure gauge or nitrous lines.
