you shouldn't have had to grind down anything to fix an issue though.
if you are having trouble finding the leak you can gas the marker up and place it in a large tub or sink of water to help pinpoint the problem area
The grinding was just to shorten the spacer. (i didnt want to buy the smaller one) I just ordered an o-ring kit from agd. we'll see how it goes.
