You can use high pressure fittings nuts.

One time I spent 3 hours looking for a bung nut. Went to every hardware store in town and even a 'Nut and bolt warehouse' and couldnt find one.

Do a google search for Innovate LM-1 messageboard. THere is a lot of talk there about hot sensors flaking. You can put your narrowband in the DP, no problem but the wideband one is just sensitive to heat. Some people even came up with the idea of using a sheet of copper as a heatsink (which supposedly works). Edit: Looks like they actually sell a heatsink on their site now. and real nice bungs for $8 http://www.innovatemotorsports.com/x...me.php?cat=250
