Markus,
It is possible, but usually it will cause the oil filter to expand or blow the gasket. There is a regulator (I believe on yours), built into the pump. It should limit pressure no a max of around 70 - 80PSI. I've seen them cause the oil filter to blow up like a ball. Others, have caused the oil filter gasket (which is rated to hold up to 150 psi) to blow out. Like I said, it doesn't happen too often, but it can happen and has.
If you ever have other questions, let us know.
