Need help

[Norton9369]

I have a 74 duster 318 2bbl been driving it with no issues took it to a car show on sat about 1.5hrs each way with no issues. The car sat on sun then took it mon afternoon to the gas station. When I got home gas was pouring off the tank. Turned out the return line rubber hose at the tank split. I put on a new line and now at low rpm the car stumbles and stalls. I did not change anything other than the return line at the tank Any ideas where to start looking. Thanks

is this idling or low RPM steady cruise, it stalls/dies?

seems to be idling fine just starting from a stop has no power and wants to stall.

Ima thinkin it's the gas you just filled up with. Maybe water in it? Could try an additive to get rid of it, like methyl hydrate. If you have a see-through fuel filter, sometimes you can see the water trapped in it. Alternatively, you could pop the top of the carb off and check the bowl. More work, but cheap, and dead-nuts accurate.

How close to empty was it when you filled up?
