I recently had the same part fail on my 2000 EVW and I repaired it in a similar way. However, I wanted to mention on mine the barbs were closer to 3/4“ with the flared ends actually a bulging a lil larger.
It’s possible on the EVC that it is 1/2”, but I wanted to mention this for the record.
But of course, YMMV ;-)
