When fuel started coming out the vent at the air cleaner I knew it was a bad sign. I found this place and sent my pump off to be rebuilt. Now it looks good and works good, too.
I believe it was also drawing oil into the intake through the vacuum end, but I can't convince myself until I see if my oil consumption changes. Here are pictures, because I know how much everyone hates pictures.

Cost was the same as buying a rebuild off the shelf and sending my old one in for a core. Seemed like a good deal.

Now I'm off to buy new oil and filter. Just in case...
