Vacuum hose size?

[celeryman22]

Hi guys, can anyone tell me the size of the vacuum hose for the headlights, wiper system, and emissions on a 1980 Corvette?

I don't want to buy the expensive hose kits just because they have the proper markings. Also, I'm only using the EGR system on the vette so I don't want to buy the entire emmsion hose kits.

I dont need the length, just the diameters inside and out if possible.

Thanks
Mike

I can't tell you the sizes but can tell you what I did. NAPA has the hoses on rolls in the back. When I replaced mine, I removed the hoses and simply took them there and compared them end to end.

Thats what I was thinking I should do, I just need to find all that hose. I was hoping I could get away with ordering it online from mcmaster carr, www.mcmaster.com.
