No doubt, you know the vacuum pump is attached to the back of the generator (alternator) in front of the turbo on the passenger side. Normally, the fat metal pipe outlet from the pump (pointing toward bottom passenger side of the windscreen) is the outlet for the brake booster. Where I'm from, that's less than a foot away because your passenger side is our driver side and the brake booster is located over there on the opposit side. You'll have to rig something to get over to your brake booster on the far side. The other smaller outlet goes over toward the fuel pump. The vacuum hose goes to the vacuum switching valve, which is connected up to the fast idle actuator, the round diaphram-like thingie on the side of the fuel pump.

It's been a while for me, and the memory isn't what it once was.

If possible, you want to try and source diagrams and manuals from continental Europe. That model Trooper was sold there with the 4JB1-T as standard, and in the left hand drive configeration you have in the USA. The model you are looking for is the UBS55. UBS17's are the 2.6 gasoline models of that era.

As an aside, I'd recommend sourcing a timing belt from anywhere the 4JB1-T was sold. Ask your Australian friend to get one for you and have him send it over with the hood scoop, if they aren't available in the USA. Change it out and count 100,000kms from that time forward. You have no idea how old the timing belt in there now is...and you DON'T want to break a timing belt in a diesel engine.
