Bought to replace an LS3 on a Genesis coupe and was beyond disappointed with this product. In fact, it wasn't comfortable at all and the rail had a little play. I constantly smelled gas in the engine bay, this item had a constant slow leak. After some research, others had the same experience, INCLUDING AN LS SWAP BURNING ON THE FLOOR. I bought a screw adapter and there were no problems, I recommend you do the same. I have included a link to a screw adapter, do not use this adapter with a plastic clip! Fuel Adapter Russell 644120
