Throttle body fittings HELP!!

["John Corbishley" <gtr1@traverse.com>]

John:

I checked the OD of the tube going into the housing because the 1/8" didn't
make sense.  In fact 1/8" is too small.  The aperture is +-3.4mm, and the
original tube's OD is 3.75mm.

Do you think I could get away with using 5/32" or 3.96mm tube in the
interim?  Would Copper be less likely to crack the housing?
