tired of the solenoid leaning toward a cable

Alright guys. I'm DONE fighting with this (choose your expletive) fuel shut off solenoid. It's wired right, got good batteries with good charge, but none of them are lasting much more than six months.



Question is, what are y'all using for a manual cable shutoff? Is it as simple as getting a generic choke cable from the parts store? Is there one specifically made for this? Any help is appreciated.
