Jeff, again, you need a 1/8 npt by 3/16 hose barb fitting for the back of the gauge. You might recall the other thread you posted showing the rear of one of these gauges, will refresh your memory of what you are dealing with. The 5/32 tubing works well with 3/16 barb fittings. Not gospel here, do as you see fit.

My aircraft gauge needed about two wraps of electrical tape to friction fit into the clock opening.

Ben, apparently the actual Cessna gauges don't go to 75 inches, they only go to about 55. I'm told Cessnas and equivalent planes only try to recover pressure loss at altitude, and minimal added boost. In my EFI converion thread someone pointed out that these 75 inch gauges were from DC-6s or other supercharged radial engines from the 50s era. The one I'm using is borrowed, I should probably returm it and locate my own.
