What size fittings do these fuel rails use?

These Aeromotive fuel rails use ORB-08 ports. You can connect -10 AN lines using a custom adapter, part number 15641.

Are these fuel rails compatible with all 4.6L Ford engines?

No, these fuel rails are specifically designed for the DOHC 4.6L engine found in 1996-1998.5 Ford Mustang Cobra models. They are not compatible with SOHC or other 4.6L variants.

What is the benefit of the full 5/8 inch ID through bore?

The full 5/8 inch internal diameter allows for a larger volume of fuel to flow through the rails. This helps maintain consistent fuel pressure and supply to all injectors, especially in high-horsepower applications.
