I'm going to replace the elbow to manifold gaskets in the off season on my 2002 5.0 MPI A1 G2 (0M345638). I know these things are NLA. I'm gonna try to do it without unplugging it. I've heard static electricity can wipe them out. I know to have the battery removed. Any other special handling advice I need to know? Want to avoid doing anything stupid to mess it up. This is a 100% fresh water boat with raw water cooling and 1450 hours. Thanks.
