cat920 3304 - injector leak - fuel in oil

[stepan]

G'day gang, I hope someone here can point me in the rite direction.

The old cat920 - 3304 - scroll type fuel system is having an issue with diesel getting into the sump, it also has developed a leak from the injectors, from the housing not the tubes.
Seems to run fine untill the injectors start leaking 5 to 10min of run time. My question is, where can the fuel enter the oil system, transfer pump? Injection pump? Somehow from then injectors when it heats up?

Any help would be great

Cheers

Just to add, the fuel pressure gauge sits at half at low idle and 3/4 full throttle which is just in the green.

I would try a transfer pump
