Just rebuilt a Qjet from an 86 Chevy Suburban. I filled up the bowl with fuel and started playing with the accel pump and the discharge is different than what i expect. Thus qjet just spits some fuel where a Holley has a nice stream. Is this normal?

That looks totally normal to me. Qjets with their small primaries are far more responsive to vacuum and velocity changes. Less pump squirt is needed compared to other designs.

Run it. If it's not enough, double check your assembly. Could be a rough bore in the pump cylinder, a faulty piston, or bad check ball.

When I bought a rebuild kit it came with a new accelerator pump that had a blue gasket/seal. According to the directions, the older seals don’t hold up well to modern gas so the seals have been upgraded. However, even the new pump seems to be a little lame in volume.
