BCbronco 3/8 Fuel Line to 5/16 spring lock

[JohnJohn]

I am finishing up my restoration and am using BCBroncos fuel line kit. Both the 3/8' feed and 5/16 return end at the engine compartment with 3/8" barbed fittings.
My stock Mustang spring lock fittings are both 5/16".

How have you guys solved this delima?

If I had two reverse flair 5/16 fuel fittings on the ends of the lines I could just use 5/16 flex fuel line to finish it off but want to know what you guys have done before I look for diffrent fittings.

I am guessing Home Depot may have the 5/16 barbed fittings.

I just went through this...I found a 5/16 inverted flair to 5/16 barb at Napa. I had to adapt from the 3/8 inverted flare to 5/16 inverted flare to get the 3/8 done. The other option I looked at - Summit has Spring lock to AN-6 adapters, then you could get a braided line made that is AN-6 on one end and inverted flare on the other.

I scrapped the 5/16 barbs for the fuel lines and used the russel conversion 5.0 and the push loc fittings and hose- here is the jegs link-

I used #6 for both- 3/8 for pressure and return. I figured I should take advantage of the 3/8 hard lines and not step them down to 5/16. It doesnt make a big difference either way unless you are running high HP
