Hello Paul
How critical is the i.d. of the 2" nominal tube for
the P port intake?
U tubes are sold by Wagner w/
  2.375 o.d. .154" wall for $51.51
Burns has
  2" o.d.     .065 wall for $33
Sharpe has
2" o.d.      .125 wall for $19.07

I understand the area is affected by the square of
the
diameter and the Sharpe tube would be slightly
smaller
than the engine port.

It will work. Burns is high priced. No question
about
it. Got a web site address for Sharp? I'll add them
to
the list.
