I don't doubt what you're saying , but wouldn't there be massive law suits if this were happening on a regular basis ? Could it be you bought knock-off hoses ? With all the products being faked and sold as name brand , it's a possibility .
Definately Gates that came from Oreilly Auto Parts. Hose is stamped with the Gates logo and fuel injected on it. Just because it says fuel injected don't mean ethanol safe so who knows.
