ABS valve leaking

Hi, I have problem with car. My ABS pump is leaking brake oil at one of two black caps (after removing black caps it I think it is called high pressure valve or I might be mistaken). You can see those two black caps on the attached picture (above abs pump motor):

After reamoving caps and pressing break pedal it would squirt out oil like on this video:

New pump is worth almost as car and finding correct used pump is nightmare because there are so many different models on this car and it has to match, as they sad to me in VW service, to model I have now or else it can't be programmed. Considering all of this facts I would like to know is that valve something that can be fixed/changed or it means I have to change whole pump and is "high pressure valve" correct name for it?

Thank you.
