I have a dual Walboro setup in my car. This week the rubber line in the fuel tank came off my pump. This is the 2nd time I replace it in one year. Its very in inside but the outside is all soft. As if the gas wore it down over time. I lost fuel pressure while my car was idling. My engine would be toast if this happened during boost. Is there any specific line I should use to avoid this problem. The current line was a fuel safe line. Should I use a nylon one instead? Hope you guys never had this problem.
