I'm slow on replying to this, but I wanted to check the fits before I 
stuck my foot in my mouth. I have several versions of 5/16" hose here 
and each of them is sufficiently snug on the IAD port. The ports 
themselves measure just a tad over 8 mm and the hoses tend to run a 
bit undersize, so this ends up being ideal.

Is it possible, Adriel, that the hose you used had been previously 
used on a different fitting? That might have left it stretched a bit. 
A hose that had been installed between the IAD and the PS, but turned 
around by mistake, might act this way. 

The port on the pressure sensor is larger and slightly tapered, so 
it's never a problem, but it could stretch one end enough to make a 
poor seal if the hose was reversed.

We are in complete agreement about not overtightening FI hose clamps, 
or any hose clamps for that matter.
