Parking Brake Cable Question

[tim71]

On my K1500 the parking brake cable hook located on the passenger side near the fuel line area is actually touching the metal fuel line. There are no other holes in frame nearby, so I believe I'm using the proper hole. I'm curious what the proper length of this hook should be? I have a hook that is a little shorter(photo attached), but it also touches the fuel line. The parking brake hook is touching the fuel line, not the vent line. The next hook is towards the front of the truck and is a longer hook, this longer hook turns the cable toward the adjusting hardware/bolt and nut. Any info or photos would be appreciated.
