I know this thread is a little older but just thought I would weigh in,
I have the lethal garage kit as well and the main thing I liked vs the Dsx was it gets it power from the evap selenoid and not a coil pack,
I too was not a fan of the Dsx plumbing and even though the lethal garage seemed better I had a hard time stuffing all that behind the engine safely,
Since I was also doing headers and other mods I cut the fuel line song the frame rail and plumbed the sensor behind the heat Sheid and added a lot of additional dei heat protectant and completely hidden and working fine more than 2 years even with the Dsx auxiliary pump installed as well
Lethal Garage kit
Cheap Amazon sensor bracket. I drilled a new hole and trimmed the access portion at the bottom
Cheap Amazon rivet nut kit using 2 M6 rivet nuts
Attached right to the coil pack cover since there is no good place to pickup from an existing stud or bolt. I figured these covers are cheap to replace, looks fairly OEM, still allows motor to flex and is not hard mounted and is easily accessible if needed. I normally would not run with any covers, but I don't really like the look of a bare LT1 coil packs/valve cover lol.
It was previously zip ties to the vacuum line with some rubber fuel line around it to keep it from chafing. Too janky for my taste to I had been wanting to fix it.

I just made my own lines and setup for my port injection
