Your question mark placement makes me question whether I should answer or not?

Is there gas in the fuel can? Is this gas in the can fresh fuel? How long ago was this working with no issue?

Cranking the engine should cause fuel to come out of the disconnected fuel line at the carburetor if there is fuel in your gas can. That is if the fuel pump can hold pressure.

The pump exchange is not complicated. Asking about the lever on the pump proves you have read some on the topic & that's good.

I would get at least a 5 gallon can to use as a fuel tank. I've just been through this sort of an ordeal with fuel supply/sending/delivery. The thread could help you if you read through it. I can't find a link to the thread, but I'll try tomorrow. (edit- later today)
