i think who 4xtoy was referring to was me. i didnt drill a new hole but made the existing one bigger in order to accommodate a larger fitting b/c mine was stripped out. heres the link

overall it turned out great. i just got back from a 900 mile round trip to new york and my engine ran great. even at 80 mph. i have about 2000 miles on my engine since i tapped the whole.
