td5 needing multiple purges after new fuel filter/housing.

I was asking you fella? I used some clear pipe in the leakoff to show air bubbles in the system, worked a treat on my old bus.

It's certainly a possibility. I read before of people using a section of clear pipe but wasn't sure exactly what valve to connect it to on the filter housing and pump.

Landy has had pump and fuel lines pressure tested - 4 bar, so no leaks and pump working ok.
It's the view of tester that the problem lies under the rocker cover - injector seals/ 'o' rings. They were done just over 3 years ago and it's had light mileage since then - so it's booked back into place that did them originally.
Appreciate the assistance/views of everyone and i'll update when I know more. ta.
