If I recall 840 came with the 248 Perkins four cylinder engine, CAV DPA injection pump. Perkins uses a constant bleed fitting on top of one of the filter bases, it removes any trapped air from the base so no air gets to the pump inlet.

There could be either a straight fitting or a banjo type fitting that the line goes from the base to the tank return, usually across the top injector leakoff line. Worth a look to see if it's plugged.
