Fuel level is on the line. I gave it 25 pumps and immediately gas started basically pouring out from the throttle shaft and the fuel level decreased dramitically enough to give the truck a rough start like it had just ran out of gas (same symptoms as when it's running and chokes up when I'm hitting the throttle). Either way I need to be able to pump my gas pedal without losing any gas through the throttle shaft. This also explains why I have been getting shitty gas mileage lately!
