Help please, I have my omori boost gauge in the dials and will be putting the in the car tomorrow.

Got 5 metres of 4mm vac hose and a metal t piece.

The hose seams to fit the back of the gauge snug but not overly tight.

Hoping the pressure coming down the hose doesn't pop it off.

Main question is, where is the best place to connect the pressure feed? if any one has a pic that would be great as my mechanic skills are limited.

Thanks in advance,
Gaz
