Boost gauge hose barb size?

Is there a standard size for the hose barb on the back of a boost gauge? The one I have is 4mm with the vernier. But our vac system seems to be 4.7mm or more accurately 3/16. Do I get a silicone hose to fit the boost gauge and just stretch it over the T piece?

i JUST DIPPED my hose in a cup of boiling water it streched over the T piece easily.
As long as you dont have a leak it should be fine.

That's what I was thinking. Just wanted to check that people be doing the same.

4.7mm seems a bit large. I've only used 3.5mm and 4mm when replacing all the vac hoses on Big Truck

Measured the hose barbs and inside of the hose with a vernier. Could be that FBW has different sized vac system?
