What is the internal diameter of these fuel rails?

These Aeromotive fuel rails have a full 5/8 inch internal bore. This large diameter helps maintain consistent fuel pressure and flow, even in high-horsepower applications.

Can I use -10 AN fuel lines with these rails?

Yes, you can use -10 AN fuel lines, but you will need to purchase the custom ORB-08 to AN-10 adapter (Aeromotive P/N 15641) separately. The rails themselves use ORB-08 ports.

Are these fuel rails legal for sale in California?

No, these fuel rails are not CARB approved and cannot be shipped to California. They are also subject to California Proposition 65 warnings.
