Default Fuel line for LS3 Intake

I'm about 90% done with an LS3 swap into my 07 Avalanche. The flex fuel line connection off the factory hardline by the firewall won't reach the LS3 intake because the fuel inlet is 90 degrees from where the truck intake inlet faces. Anyone have a solution for this?

I was going to make a short piece of -6 line but I'm having trouble determining what fitting I need for the hardline by the firewall.

Based on that picture I would do a straight fitting off the fuel rail feed and a 90 fitting off the stock feed. It will need a very short piece of hose inbetween.

I plan to do a short piece of -6 hose, I just need to know what fitting I need on the firewall side. Can anyone help?

Figured it out. I was working from pictures and didn't realize that the flex line is not a separate part like on Corvettes and GTOs. So an AN adapter to a female/female 90 to a male EFI adapter should do the trick.
