Two ways I can see to do this. One is simply buy long rivets, the other is to drill and counterbore. That is the path I took.

First you need to cut open a rectangular hole for the sensor. I use an angle grinder with cut off wheel. Not the best as it is not a clean hole and the cutting disc can load up with aluminum.
File work will clean this up.



Time to drill and counterbore. Rivets required about 3/16" of material to fall into grip range.



Rivet tool would not reach into hole so washers were stacked till flush plus a bit more.

Make sure mount is clocked the correct way - the blade style only flow one way.



Test fitting in engine compartment. I will use sealant around the perimeter of the mount - no leaks here! Pipe will be scotchbrited then cleared after sealant dries.

I hope there are better mounts that already have mounting hole and rivets ready to go...

Very impressive work!
