I have no choice. I have to convert the efi system to work with a bypass regulator and also install a return line. The cost of fittings and lines will be an easy 250-300 bucks.
But I am doing it all in 3/8. If you have to do it all over, you might as well. Not much of a cost difference between the two.

But if you dont, does anyone have a good argument for the 5/16?
If it's in great condition...and I know where rick is coming from, it's a tough pill to swallow having to do it all over. It's definitely a tough call since he's feeding two carbs.
