Default stalling

i have a 73 l48 auto with a qjet. when driving around the engine sometimes wants to stall or cut out, it seems like a fuel problem because if i catch it in time and pump the gas it will run. i don't have the car that long and i am trying to get any bugs out. any suggestions on what to try first?
thanks a lot

at you at a stop or near a stop when it wants to stall? Mine was doing this and a bit of carb tuning fixed it.

If its while cruising then I'd say fuel pump! Might sputter a little from time to time while at cruising speed. Fuel pump is a quick swap.

I would test the fuel pressure first before I went and changed the fuel pump

Check the bowl levels. I have a Holley which did the same. Combination of heat and not enough fuel caused starvation. Check the issue on a hill, if it wants to stall this could be the problem.

Sorry, you stated it was a Quadrajet in your first post

It certainly does sounds like a fuel problem.
If the ignition is in good order, timing is set correctly, I would start with replacing the fuel filter, if that doesnt clear things up I would think about a rebuild on the QJ

Did this car sit for a long period of time?
