My throttle cable kept getting looser and looser. I tighteded and it would be loose again.

So I started inspecting.

Where the cable connects to the throttle pedal there is a rubber buffer or gromet. This had torn and caused the line to keep getting loose.

I searched for the gromet but it looks like it comes with the throttle cable. Which I will replace. But is there any other way I can replace this so it won't happen again?

Has anyone had this happen?
