Just riding along on my CF Moto Helix clone, and it died. Got it home. There is no vacuum to the diaphragm fuel filter. Any idea?

Major crack in manifold or the vac line to the pump would be my first guess

Are they all the way thru the side? And what's the vac line look like? It's probably worse than that

The lines are good, like new. It's the fuel pump. I made a mistake when diagnosing, I checked the wrong line for vacuum. There's good vacuum at the pump, it's just not drawing any gas. Got a new one on the way.

Turns out, I was wrong. It's the pump. I ordered a cheap one, I'm poor!
