FD Fuel Line upgrade question
So here it goes. I'm looking into upgrading the stock rubber fuel lines in the engine bay and in the rear by the filter/charcoal canister. They are old and have seen better days. I would like to use AN fittings from the hard line to the upgraded stainless steel however, i can only find adapters that fit 5/16 to AN -6 (apparently an AN -5 is rare). Do you guys suppose using larger diameter "soft lines" would adversely effect the fuel system, recalling the fuel would "bottle neck" at the hard lines.
I cant really justify upgrading the stock hard lines to 3/8th as it doesn't meet my power goals.
Thanks in advance.

Be careful about AN lines, I had my FC converted over to them and I had one split lenthwise (internal rubber) on me, got lucky it was when i was getting the car out of winter storage and i was watching stuff real close.

I just up graded a aftermarket fuel rail and injectors - etc using proflow AN fittings and braided lines - I would recommend asking a shop for help, If your running a aftermarket ECU this set up and maybe a larger intake pump would help you with giving you plenty of fuel - When using on the track i would even add a surge tank from Turblown.com

How did you connect the hard lines to the SS braided lines on your set up? Ive seen guys use compression fittings but i think there only rated for 50 psi or something, and i feel like that's cutting it close.

You can use 5an tube nuts and sleeves. The end of the hard line needs to be cut off and flared using a flare tool with 37* angle. Then you can use 5an to 6an adapters. It's a pretty common solution.
