getting fuel up to that point of the engine can be a task. especially if fuel lines are not perfect. you are trying to suck gas about 25', to a point that is probably 12-24" above the fuel level in the tanks with a pump that is borderline able to do that task.

I highly recommend an electrical pump back by the tanks at least for the aux side... simple, helps vapor lock when needed and priming of fuel system for cases like this. 10' or less of fuel line, and it should be quick to give a gravity feed of gas from some other gas source. get the engine started quick that way, then hook up the fuel line stock and it should start sucking. also making sure gas tanks are fuller helps. I know when I have drained out gas, it usually takes about 15 gallons in the tanks to get fuel flowing right at first.
