I have a 66 GTO with 389 and Tripower. Lately started having issues with the fuel supply. Runs fine most of the time. Problem starts when I get low on gas. (1/4 tank). Starts to bog down when I accelerate going up hills. Before long it will happen on straight away too. Bogging leads to sputtering and smoking and finally stalls. Fires right back up and idles fine. Press on the accelerator and it stalls again. I can make it to the gas station and fill up. Let it sit a while and it will run okay until the gauge reads low again.

Not sure where to start. Gas tank? Fuel pump?


I had the carbs, sending unit cleaned. The mechanic dropped the fuel tank to look for trash. Didn't see anything to cause concern. It is an old tank. Replaced the fuel filter and the dirty air filters.

Anyone else had this issue or have a suggestion?
