Haven't done this myself, but in theory you could take all those voltage controlled air valves from the 13-B induction system and, controlled by a simple rotary switch to 12 Volts, select the tube you'd want to connect to the ASI. No need to bring all the tubes into the cockpit.

There is quite a bit more but here is the key
    

part.   Use an extra 
  

airspeedindicator to measure the pressure at
    

various places around 
  

the heat
exchangers, especially the 'front' side.

    

Tracy, this is just such a way cool idea!!  It
wouldn't take much work at all to run a bunch of
temporary 1/4" ID platic tubes to points all over
the plane and cowl, with the ends all terminating in
a nice row on a block of wood.  With a brass insert
fitted to a piece of tube coming out of the AI that
would allow the AI to be switched between any of the
various ends, a survey of relative pressure across
and within the entire ship can be made in a single
flight.
