2005 flex fuel replacement fuel lines?!?!?!?!

does anyone with a '05 flex fuel suburban happen to know of anyplace to find fuel lines? I am having a really hard time finding anything that it flex fuel for my year. And yes, although most online sited don't make a distinction between the line sets for flex vs gas, they are different and will not swap.

Here's what happened. The flex fuel vehicles have a FCS (Fuel Continuity Sensor) on the drivers side frame(under the drivers feet). There are two short sections of flexible fuel line that connect to the FCS. The way the lines are installed, the two flex pieces are able to rub against each other. Last week, after driving home from work and pulling into the garage, I noticed a really strong gas smell. I looked underneath to see fuel spraying out of those lines(which are really close to the drivers side cat convertor by the way).

thanks in advance for any help you can offer.
