Drill bits and step drills tend to grab,wooble and tear at the plastic fuel cells,especially when your trying to make a large hole for a #8 balkhead fitting.IF your hole is a little loose just use teflon washers which are recommended for both sides of the fitting.



sorry but i disagree totally. using a step bit goes in like butter and bulhead goes in nice and tight with a teflon washer.
the jaz bulkheads are the best by far.
a hole saw gives you a ragged edge and i havent liked the holesaw fit, it seems to be too loose.
