Fuel fitting question.
 

Looking at AN fittings for a project, and want the stock GM Poly lines to be able to connect. Would these fittings be the correct ones, or be capable of slipping the poly line over it :

Or do I have to run these, which would require using the steel lines with the double ended barbs to slip into the quick connects?

I'd use the second style.

You have to use push-lok hose with their fittings

Second style but be aware you cannot use more than 12 inches of rubber hose for anything on the car if you want to be NHRA legit.

If you use this style you wont need a male to male fitting to connect to the hose
