With truck on empty(arriving at lake house on T-Bend) it dawned on me that perhaps I could siphon some gas from my 201d. NOT! Is there an anti-syphon devise on year 2000 cobra tanks? Found a neighbor with new Triton and after several attempts of blowin to check if we could hear gas bubblin we managed to suck enough gas into 5 gal cans to fill my truck tank up so I could get back to Houston. Question isss Do Cobra's have an anti-syphon devise or did I just not twist hose enough to get into tank??
