Interesting thought Ed. Right now I am using blue silicone fuel proof hose from the Marine industry. Seems very stiff, but maybe not stiff enough. A have them set up so my carbs are about 1/16" away from the 1 1/4" head intake tube. I was thinking the shorter the better.... I have not played with that.
Will take a look thanks!

The rubber flange that can be purchased for a Mikuni spigot carb is about 40 - 50 Durometer... Sorta like the the soft Continental motor mount bushings... A real stiff hose might not be a similar spigot mount... For sure the spigot should not contact the intake pipe which would be easy to do in a short coupling or bridge the gap with a clamp... Until the VW has about 50 hours on it there are more resonances running thru the engine - that's where some flyers have used the mercury based prop extension balance disks effectively...
