vac lines

[henry 008]

where do I find the original spec for what size the vaccumm lines are for the carbs? I've heard 3.5mm or 5/32 or 9/64 hose with a .100 wall is best.
3.5=.138, 5/32=..156, 9/64=.140, 4mm=.157.

5/32 ID is what you need

3.5 mm is factory stock size. But 5/32 " works too.

thanks guys! just happened to have 4mm here at work, so that's what I'll use.
