On take off the other day I was up to 2 Psid by the time I went wheels up. That was with the gold box 95% closed. Does anyone happen to have a dukes manual?

>>> I'm looking for a minimum thickness vacuum hose just to hold the dukes pressurization valve open on takeoff.  Right now I have a 1/4" i.d. .64" o.d. big fat rubber line.    I don't see anything on McMaster Carr that is thinner wall.  But given it probably needs to handle maybe 10 psi of vacuum, the big fat rubber hoses seem like overkill.
