I would say loss of fuel prime means air is getting in somewhere, so it stands to reason fuel could be leaking out. However, if it is a tiny leak, and there really is not much pressure on the fuel system, it is possible to not see any leaks. At least, that happens on VE cars. Cannot say I have ever seen it on a PD, and I have never seen a bad lift pump on a BHW (on BEWs and BRMs, yes, lots).

You can remove the thermo-tee on the fuel filter and see if it is full of fuel. If there is a loss of prime inside the head, where the tube feeds the injectors, then you'd see the crankcase oil slowly being fueled up, but it may not be very noticeable at the amounts we may be talking.
