All the fuel lines are sealed with o-rings. The connection that is leaking is either loose or needs to have its o-ring replaced.
The tank should not be pressurized AT ALL. Which cap is the fuel spewing out of? Saddle tank cap? Cap on top of the hood?
For fuel to be "spewing" out of the vent holes in the cap, the tank MUST be overfilling. Even if you pressurize the tank, the air will push the fuel down and away from the cap, not up and towards the cap. Fuel CAN NOT spew out the vent if the tank is even slightly less than full. The tank MUST be full right to the brim for fuel to spew out the vent, and for it to spew continuously, it must be getting additional fuel from somewhere to keep the tank full right to the brim.
Side note: Never fill the tanks right to the brim. Fuel expands as it gets warmer, so if you fill 'er right up and leave the tractor in the sun, fuel will spew out the vent holes.
I suspect that there are selector valves somewhere that allow you to select the saddle tanks or the main tank. It may be pumping fuel from one tank, but returning it to the other due to an incorrect combination of selector valve settings.
