Fuel Hoses Lines/piping And Fittings problems of the 2001 Dodge Grand Caravan

Ruptured fuel line spraying gasoline onto muffler. The fuel lines are plastic and are attached to the fuel filter and are replaced together as a unit. The plastic line had a quarter inch rupture. This filter had less than 30k miles and was about a year old. Why does Chrysler use plastic fuel line? I do not know the cause - a weak inferior plastic or a sharp stone perhaps. Either way, it does not matter. I have never seen a hard plastic used for fuel delivery. The old style rubber fuel hoses would be much better and safer. I am thinking this plastic is used because of the flex fuel option but I am not a mechanic. I am glad my vehicle did not catch fire. I was lucky. After replacing the filter with a new one from napa one of the fuel lines would not stop leaking. I had to return it for another non leaking filter. Because of this I am also concerned about the quality of replacement parts as well.
