Hose from fuel cap to fuel cell leaks - replacement suggestions, please

[chris-CMC#35]

Getting #35 back into shape.

First step: pour in some fuel.
Second step: watch a big pool of fuel form on the garage floor.
Third step: get underneath the car, and discover that the flex line carrying the fuel from the filler cap to the fuel cell is oozing fuel.

The hose that's on there is BellowsFlex.

Since I have to drop the fuel cell to replace this hose, I would like to have a high degree of confidence I won't have to do this again.

Any suggestions?

Thanks
