Have you checked that.

I've never had that problem myself, but I have heard about it. If you have the manual lever in the wrong position, it prevents the diaphram from being actuated...then it won't pump...

To add a bit more in response to the original question: Five gallons is plenty to get it running with a dry tank... Check also to ensure that the vent lever on the gas cap is open (if you have the style with the lever) or the entire cap itself is slightly loose (the partial rotation "back" from being fully tight where it will vent but not leak) if the newer style so that you can get air into the tank when pumping. The vent line from the tank to the air intake elbow is sufficient to vent when fording a short distance, but not for a long ride. Usually, this manifests as a truck that runs at idle, but has no high end, no power, and poor throttle response, but check it anyway...
