yes, i posted before about the explorer i own and i changed petcock valve and fuel lines, and still having problems.once turned off and next day i try to start it will start but won't stay running, until i take off gas line to carb and no gas will be coming out of line till i lower line and start to let gas come out it will run fine, until the next shut down? would having more gas in tank help the flow like a 1/2 of tank?
