I know from your pic it looks as if the leak is indeed the seal still leaking, but you should do the O-ring as well if you're going back in there.
They age harden and want to shrink and on my first 9000 the O-ring had split clean thru, and as it happened right at the bottom, making a massive oil leak of pressurized engine oil.
You don't actually need big internal snap ring pliers to get that snap ring off the oil pump cover, you can if patient pry it inwards at one of the end holes, then work a small screwdriver in between it and the groove, and another small screwdriver under the end of the snap ring, working it up as you pry it further out. Pry with one, slide the other along as it comes out of the groove, pry some more, slide some more. It's hard for about the first third of the way, gets easier, then about halfway around it just pops out.
Some big pin punch or similar to poke into the end hole helps.
Similar on reassembly.
With the cover out on the bench installing the oil seal goes easy.
That advice about installing it at a different position holds but now you can't easily judge where the original was set at. Saab 9000 doesn't get a lot of sand up there past the underbody pans, so the seal hasn't probably cut much of a groove anyways, not enough likely to need one of those sleeves.
