fuel line size for 67sb?

[Larry S.]

For C2's-What is the size of the fuel line on the gas tank side of the fuel pump and on the carb side of the fuel pump?

Are the same size lines used on BB cars as SB cars?

Thanks.
Larry

3/8", all lines, all engines.

Larry -- To expand on Joe L's answer, yes, all C2 fuel SUCTION lines [tank to fuel pump inlet] are 3/8" OD; only the length and end bends changed in the vicinity of the pump.

But on the pump-to-carb line, small blocks were 5/16" OD on the discharge side of the pump. Big blocks may have remained 3/8", at least up to the Y-block split [for '66 L72's and '67 L88], and in the case of tri-powers, 3/8" all the way to each carb.
