hi guys, I want to make my fuel return line in braided, I research but not find what I want to do. I want only from the regulator to the hard line in the firewall not the entire line to the tank. I need to know the O.D. of the return hard line cause ATM I not have a caliper. The most common is 5/16 but looks like to small, I need to put a compression to AN fitting.

thanks

 

I believe mine on my 97 was 1/4. I kinda fragged it doing my HG swap two weeks ago.

 

1/4 is smaller then 5/16ths ... when I did mine I couldn't mind anything for the size either.. its a very small odd ball size for an fittings.
