Oldie but an update. I had to change my bulb due to a cut in it. Found it when loading the boat last time. Cut it open and was in perfect condition. Now it was a thicker rubber then the previous one and the new one I got but that really doesn't mean a thing I guess. The new one I got is blue and pretty pliable but is for ethanol. Again I only use ethanol wit half a bottle of seafoam in each 14 gallon tank and about 1oz of marine stahbil in each tank. So almost two years and the system is rocking. That reminds me--I need to pick up a new fuel filter
