Culprit: 1966 Ranchero, 200IL 6, Autolite 1100 Carburetor Problem: When driving under hard acceleration, the vehicle runs out of fuel. I can take the fuel cap off and there is a major inrush of air. I can then run for a little while before the problem repeats. Repairs done: Fuel tank removed and cleaned, fuel lines cleaned, filter changed, new vented fuel cap. Any suggestions on what to do next?
