Brainstorming ideas for coolant crossover on Air-Gap intakes

I think where I live on the eastern edge of town is closer to 4000 feet, I'm a solid 15 miles from downtown Fort Collins which is visibly closer to the mountains.

I'm just gonna check my cranking compression it's the only way to know for sure (IF the gauge is accurate) and it's something I should have done long ago in the 4 years this mill's been running.
