I just hunted for the last time I detailed the process and can't seem to find it, other than this one.

Once it's removed from the bracket, I just zip-tie it up under the tank. I made sure none of the lines were bent or pinched. I also wrapped the regulator in heat resistant foam. And, I wrapped the lines in a heat insulation material (details in the post link above). It's not going to get much air up there. So, you have to keep it cool.
It's not a hard mod and certainly cleans up the LH side of the motor.
