An interesting idea.  Having started the Pyrex idea, and given it up, I'll mention what I'm now planning on building over the holidays.  I got a section of acrylic tubing and a section of clear PVC pipe from Aircraft Spruce, advertised as appropriate for gasoline.  I have a pair of AN842-4 Hose Elbows.  These are 90 degree elbows, 1/8 NPT on one side and a hose barb on the other.  The tubing (not sure which kind, yet) gets tapped and the fittings glued in with Hysol for strength and for sealing.  The hose barb sticks thru the panel and the Tygon tubing fits up against the back side and hose clamped to the fitting.  Will probably have a grommet thru the panel.  Push the fitting thru the grommet and stick the tubing on the protruding end.

My panel will have a teak veneer.  The fittings are brass.  (Should look classy, eh?) The back side (outside) of the tubing may be painted white and the threaded portion of the tubing may or may not be painted black.  I plan on proof pressure testing this to some reasonable value, like 30 psi, with a bicycle pump.

Most of this idea was swiped from two other guys on this forum.  I'm sorry but I did not record their names.  I'll plan on taking a photo and sending it to Marv.
