1966 Fuel Line Size

[earlbuddy]

Looking at my 1966 parts catalog it shows the three fuel lines.
Pressure, Fuel In, and Fuel Out. It also shows small and large clamps. The Fuel In and Out use the same clamp. Anyone know the two hose sizes used?

Just use plastic cable ties with a radius hesd on them.Always check and double check for fuel leaks after any fuel system repair.

I need to know the two hose sizes. 1/4, 5/16, etc.

Thanks. I did find pulse is 1/4". Since the clamps are called large in the parts manual for the fuel in and out, I'm assuming they're 5/16".
