May have solved Braided Fuel line problem!

Fuel systems seem to be the hot ticket right now, doing the same here.

The two fittings from Summit, are for newer Mustangs and LS1s. The list a 5/16 and 3/8, but we need a 1/4" and 5/16", so use the 5/16 for the feed line, the return we are still SOL.

The other three links:
Steeda showing a 3/8" to -8AN, too big for us. The other part dual -8AN to inverted flare is the same as your stock hard line. You need a spring lock to connect the stock nylon/rubber line.

1st Aeromotive is what Steeda is selling

2nd Aeromotive is everything needed to connect to the stock nylon/rubber lines. You can go this route, then work the smaller Summit part into a -6 to dual -8 (but you have to make it.

There's a large thread on a competing site that has been battling this and one poster found these they are used on the pick-ups and return at the tank. flare-less fittings and you can adapt to through outher fittings what size line you would like
