Sorry, didn't see this last night and it looks like you have sussed it now, yeah your not ment to have a seal on the vac pump, the vac pump seals in with an "O" ring as that is how it gets its oil feed
there are 2 in the kit because the kit will cover other cars/vans using the XUD9 that don't have a vac pump located there.
