7MGE Intake tubes degree angle and diameter size?

[toyota.s]

Does anyone know the degree angle and diameter of the 2 rubber intake tubes? They are discontinued from Toyota for the 7MGE. I found a website that sell silicone tubes, but to many to choose.

Also, I was looking at pictures, and it there is a vacuum hose that is attached to the first intake tube. Does anybody know where that leads to?

I have a 1987 Supra 7M-GE Auto.

for the vacuum this may help. I think the one you are pointing to goes to the charcoal canister but I don't see the BVSV installed (23262).

If the vac line is attached to the first intake tube after the air flow meter then it is the power steering idle up circuit. That line goes to a valve on the PS pump. (17630 in the drawing above)
