Replacing Diesel filter
Never done one of these before. Are there any tips to stop air getting in to injector lines/pump?

You'll have to bleed it whatever you do, but pre-filling the filter before fitting will make it easier. You may find you don't have to bleed the injectors.

There doesn't appear to be any bleed screws anywhere, so was going to losen off a fitting between the pump and filter and do it that way.

Is there not one on the filter housing? My old one had one on there.

There is a bleed screw on the filter lid, but having never dealt with Diesel injector systems before I was concerned about how much air in the system it could deal with if any?

Fuel filter
Top up the new filter with fresh diesel. Smear a little fresh engine oil on the thread before screwing into the filter housing. Run the car for 5 minutes on completion. Job done.

I'm not familiar with the Trooper engine but on most I have dealt with, if you just put a new filter on and start the engine and let it idle, it will bleed the air out OK as long as you don't rev it. Rev the engine and it will stall and need bleeding properly.
Common rail and unit injectors aren't always that easy, but anything with a mechanical lift pump is usually pretty good.
