Default Holley fuel rails on returnless

How would I connect my stock fuel line to the Holley efi fuel rails that come with the Holley hi-ram? There are -8an connections on the rails

Adapter from the stock line to -8an then to the front of the passenger rail then crossover on the back? To avoid alternator clearance troubles.

Edit: on a 2004 Silverado, returnless style system. Dual intank walbros

Bump, really need help!

Anyone know if this would work?

Seems simpler than a crossover. Use this on the back then plug the front of the fuel rails?

I would put in a Y on the end of the stock line, then from the Y to both back ends of the fuel rail. Cap the other end of the rail.

What you linked is for a carb. You need fuel injection rated lines.
