Plugging water passage in injector housing. - ZR-1 Net Registry Forums

When reading the systems elimination article on this subject, I thought they said to use 1/8 inch plugs in the housings. I just tapped and plugged mine using a 1/16 inch plug. I didn't have to start by reaming the hole to fit a bigger 1/8 inch plug. All I had to do is tap the hole as is and put in the 1/16 inch plug. The new plugs are 5/8 inch long, go all the way in flush, are nice and tight, have Permatex thread sealer on them. I don't see why this wont work just fine, anybody done this? agree or disagree? Jim
