Alright, so first thing this morning I went back at it. Figured the spring HAS to be in first, irrespective of what I think I saw. Now, since having the valve in one way was wrong, my next move was to reverse the valve so the needle side goes in last and is pointing toward the connector and ps hose out of the pump.
Well, that worked. The second attempt went MUCH easier and again, the connector broke loose, so I had to really get something to hold in in place as the hose was being removed - like proper tools!

Thanks for reply mate, that's the diagram I have. The differences however between that diagram and my hardware is that valve (24) looks nothing like the valve I actually have, and there are no retaining ring (22), filter (23), and o-ring (25), as depicted on the diagram, at all.
So for those of you with parts other than what's on the diagram remember, spring first, valve second, with the needle side last. Good luck.
