Oh.. I got you.. Yes the grommets I ordered are very similar to the Uniseal ones.. these go in the tank wall as well with a beveled edge to the rubber as it goes in.. you get like 1 1/2" of the pipe actually into the tank..
No issues.. makes me happy.. my tank is 8" in height and I'd rather just buy the one for $192 (15 gallon) and then do a 3" on top for the toilet and the 1 1/2" on the side top edge for the sink/shower..
I will be sure to have some type of p-traps to keep the 'stink' from creeping up into the shower/sink..
