I've put on extended diff breathers. The one to the rear diff was fine, but where is the front diff breather?

The workshop manual reckons there's 4 hoses near the front diff.
2 go to the actuator, 1 goes to the vacuum tank, and the last is the breather, which is meant to run along the top of the axel to the passenger side. I only have 3 of them.

Upon sticking my hand as far as it will fit, I can't feel any breather.
It's on a '93 NH GLS V6.
Thanks guys!
