Where can I buy just the spacer and hefty factory o-ring that goes on the fuel pump? I'm talking about the ones picture in the upper right hand corner of this pic:

I can't seem to find a number for them...my o-ring is partially torn and the fuel pump seems to be missing that spacer. I've got a walbro install kit but with the o-ring and cap in that, it never seems to snap into place like it should.

Part numbers or suggestions?

Car isn't getting any fuel and I'm guessing this is the issue...
