Vacuum hose inside diameter

[440 PHIXX]

I’m having a hard time finding the right size vacuum hose for distributor advance and vacuum pull off on the choke. I think it’s 3/16, but Autozone doesn’t have it. Am I wrong on the size? All they seem to have is fuel line which is much thicker.

Think it's more like 1/8" I.D. Similar to wiper fluid hose. I have purchased it at Advanced Auto Parts.

There you go! 3/16 sounds good

Edit; checked with some drill bits on a hose, 5/32nds might be a better choice

Remember that TUBING is sized by the I.D. by WALL THICKNESS not the O.D......but what ever works is ok...

its 3/16. Make sure it is designed for vacuum, not pressure or it will collapse.

An old thread...but does anyone have a source for this vacuum choke pull of hose?
