Fuel Line upgrade

For my Termi/GT500 conversion I will need to upgrade my fuel line from 5/16 to 3/8". Any advice on how to do this would be great. I've ordered the hard line and would like to use an6 fittings and braided line to the engine. That seems fairly straight forward, but it is where I need to connect to the tank is where I'm stumped.

What hard line did you order? So you want to use the hard line and braided line?

I used this adapter in my 01. Used it to upgrade the stock lines to -8.

I have a coil of 3/8" I'd copper nickel fuel line which will replace the 5/16" line already there. That will go to the engine bay to a return style pressure regulator then to the fuel rail. The regulator has 6an fittings. I am not married to the braided lines however.

I'd scratch the 3/8" and run some -8 at a minimum. Plus routing the line is a lot easier than dealing with hard line.

What not get an aftermarket fuel hat. Then go to a place like www.aeroquip.cc and order PTFE lines and Aeroquip fittings and run a whole new setup. That is what I did.

What they said^^^ if you don’t want to buy a new hat do -8 braided line. It’s easy and works great. Did it on my buddies Mach 1.
