Per Sect 51-07, Steps 1-3 added firesleeve to wire & cable bundle at firewall pass-through (FF00001 Firewall Penetration Fitting). Called Vans Prod Support - and Mitch Lock answered, President of Vans Aircraft. He was filling in! I told him my bundles were so tight in opening, I didn't feel I could insert the rubber firesleeve - especially the RH one. He described how he encountered same issue, and used "anti-short bushings" instead when he built his RV14a. Key is isolation of wires from metal edges front and back. I ordered some 1" dia size (no local stores carry that size). I inserted firesleeve in LH hole...with great effort, taking over an hour to push in. I plan to use the bushings on RH side. Both will be filled with hi-temp RTV, then wrapped with second layer of firesleeve.
