I have a 46 WC with big bore carb and larger governor and I am new to pulling. Should I run a larger fuel line or keep the stock line. Any advice would be greatly appreciated.

While a larger diameter line or hose won't hurt anything (unless your hose has a droop in it) the size of the hole in the carbs inlet valve seat is what controls how many GPH of fuel will flow by gravity into the carbs fuel bowl. How much fuel rate(GPH)you need will be determined by RPM's, carb venturi size, and cubic inch size of the engine. An electric fuel pump solves any gravity system supply deficit. More gallons in the fuel tank aids a gravity system. What is a "larger" governor ?
