I think as long as you tighten it up really good it should seal up fine

It's not a regular brass/stainless freeze plug if that is what you are thinking. It's a 1 3/8" expandable plug. It has a bolt that tightens it up...just remember, you are tightening it into a plastic intake, so make it snug, but don't crank it down too hard.

you will probably have to expand it a bit before you can get it to tighten in the intake without turning

the rubber expanable freeze plugs at oreilly. They expand upto a 1/4'' so get one that will barely squeeze into the hole and tighten it. Or go and get a FAST 90 and forget it. lol

Is it plug that is 1 and 3/8 inches wide?

Or

Is it a plug that goes from 1" down to 3/8" ?
