depends on where your sending unit is located. on a Fury like mine, the sending unit is at the front of the tank and often submerged so I didnt want the wires going through there as I expected that would leak. that's why I did the hole and grommet at the top of the tank. I wounldnt call it half-assed, it works fine, is leak-proof, and safe. On your own car, it's just up to your preference
