Excessive fuel usually makes black smoke. To go through gas that fast, probably the best suspect is a leaking fuel pressure regulator, but I don't know if your engine uses one by the engine. If it has one on the fuel rail, remove the rubber vacuum hose going to it and check if it's wet with fuel inside. Replace it if it is. I suppose an injector could be stuck open too but that would not be common, and I don't think it would use fuel that fast.
