Fuel Lines

[Gumby]

We have our fuel pump mounted such that it is submerged in gas and recently we have found that the rubber fuel lines are disintegrating because they are submerged. We have tried high pressure fuel line as well as steel braided line in the fuel cell, both giving the same result. Last years car used the same set up and didn't have these problems. We have determined that the ethanol content of Sunoco Ultra 94 is causing this problem (which may be higher than last year at this time)

Has anyone else had this problem and does anyone else know of any flexable line that can be used (and available within the next week)??

Thanks
