Rubber pitot tubing size?

[Thumper]

Hello both the rubber hoses connecting the pitot tube to the metal tubing inside the wing on my Citabria are so old and brittle they have actually cracked and fallen apart. Checked the parts manual and came up with part number 7-786-3 "rubber connecting tube" but it provides no sizing info on the diameter of the tube nor does google seem to yield any results. Anyone with experience with this part able to give me the size needed for replacement? Thanks.

Rubber tubing is just a standard part. It is sized by ID, so measure the OD of the barbed fitting or tube it slips onto, and buy that. Gonna be 3/16", 1/4", or 3/8".

Right was just trying to save a trip to the airport to take a measurement and not even get to fly afterwards! It may vary for others but on my bird looks like the ticket was 3/16" ID and 5/16" OD tubing.
