what to use to tie up fuel tank wires?

[jt1583]

I put in my walbro pump and the wires are pretty much just loose kind of dangling around probably when fuel moves back and forth. Im the kind of person that thinks the worst of something and feel that unless i secure them they come undone and spark and boom so is there anything I can use in the fuel tank to secure the wires to either eachother, or the fuel pump mount.

possible ideas
electric tape - dont think itll hold up to vapors
zip ties - would they last a couple years tho or would the fuel destroy them eventually?
slice fuel line open and sheeth them in that - best yet, but would still like to be able to tie them up

any input appreciated
