Dual Feed Fuel Line Setup

I personally prefer the hard line. No the spacing is different on some carbs so you’ll need to know the center to center if you go hard line. Also the threads for the carb bowls are different if you need to swap them. Pressure gauge port is a good idea for troubleshooting. How ever personally once pressure is set or known I’d remove the gauge. The heat and vibration plays havoc on them and a fuel leak on the manifold or anywhere is never a good idea.
