Yanmar 2GMF Fuel Mystery

I can hand prime with the lift pump the secondary and injector pump bleed screws. Engine starts and runs for 3-4 minutes then stops.

The secondary fuel filter cup is almost dry. The engine uses the secondary filters fuel and stops when its empty.

I have replaced fuel lines, primary fuel/water separator, new lift pump
filters and have spent much time looking for leaks etc.

It was suggested that the lift pump arm goes under the cam inside the engine. I have the new lift pump arm against or on top of the cam. What is correct?

It seems the lift pump is not pumping fuel to the secondary fuel filter as the engine runs.

Any help will much appreciated, Thanks!
