im thinking the fact that its 16* out that may have something to do with this but...when i went to fire up my monte carlo that has a Holley 650 dp, there was gas spraying/pouring out of the vent tube on the primary side. My guess is something iced up since the last time i drove the car a few days ago this wasnt a problem.
just curious to see if this has ever happened to anyone else here?

Sounds like the needle and seat stuck open on the primary side. Some debris might have gotten lodge in there. I would take the needle and seat out and clean it but you'll have to adjust your float.

Agree with the high float level. Might also be to high of a fuel pressure.
