2.0 Tdi 16V BRD Tandem pump full of oil

Hi
Suspecting that I'm getting oil into my fuel, I just pulled the tandem pump off with a plan to clean out & fit new seals. I was surprised to find the vac pump side awash with engine oil; so I figured the seals are well gone... or is this normal?

Sadly no pictures, I just started cleaning it up.
It wasn’t “full”, there was just lots of oil on the surfaces and in the rotor and paddle.
I had recently tested the vac system and it was pumping fine & the one way valve has kept the oil out of the vac tubes.
I’ve taken it off to fit new seals as I suspected oil in my fuel, I’ve done the injector seals at the same time.
Does this vacuum pump normally run dry then?
