Re: Merc KE-4 gas tank question

At the risk of sounding very old school. you do not need a tap. You need a machinist with a
lathe and a thread gage. The taps in the larger sizes are uncommon and the gas cap thread may be a nonstandard size. Making a thread restorer by cutting the correct thread on a piece round stock of the correct size is not Rocket Science difficult. Richard White ( plug ) makes OMC tools and may wish to expand his offerings into the Dark Side.
Those of the current generation may find it hard to believe. but. once upon a time in America people fixed things and even improve them as a result.
