Sorry to disagree with everyone on this.
Best spot is in front of the radiator.
Next best spot is somewhere in the engine compartment. Like under the battery. Use it on a tilt blowing downwards or back toward the firewall.
If running hard lines is to difficult, AN lines can be routed to where you want it. As an example, to the rear of the car above the axle in front of the gas tank blowing downwards.
IMO, air flow is the issue where it sits now as well as the danger of road debris’s smashing it.
