What causes a 1981 for bronco to vapor lock. We have changed the fuel pump, fuel lines, fuel filters and placed a kind of heat wrap on the fuel lines. Once the temperature gets above 90 the truck will stall out. If I take off the gas cap and the gas line at the carburator, then replace the gas line and wait about 1 hour it will start. Any sugesstions will be appreciated. Sherry Easton
have the same problem?
