Got the jsm coupler. Their website said it fit genesis but wow no room for error...

For those who eventually purchase an aftermarket jsm coupler- here’s what I did to get more wiggle room. I cut a 1/4 inch off the barb so that the coupler wouldn’t have any chance on rubbing against or hitting the engine coupler. I put a metal object underneath the barb Incase the saw went threw, then used a file to clean up the edges, and get a towel to clean up any rubber dust from inside the barb. Tighten the hose clamps like your life depends on it, and check them after first use/periodically.

So you cut the actual raised ridge ‘barb’ off the end of the plastic sleeve, correct?
