Hi! Cleve.
I made really good clearance holes for any electrical cables,
throttle,choke, heat cables and fuel pipes then with them central to the
holes I applied a fire resitant mastic in abundance to bothsides of the
holes , bit untidy but holds the item fixed from any fretting, and it's as
fire proof as you'll get.
The rudder cables go through slots and the locus of travel is difficult to
close off but Europa do have strip fire resistant rubber like material to
attach like flaps to close out the holes. I have used this material pop
rivetted to the extremities of the stainless firewall to act like a draught
/fire excluder fitting tight to the firewall particularly covering the
bungee rope over the top landing gear frame member.

Subject: Going through the stainless portions of the
firewall
Collective wisdom -
I have not yet purchased the manual for the engine installation (doing the
Jabiru 3300). My question deals with the best way to handle running fuel
lines,
cables and wiring through the Stainless Steel portions of the firewall.
As an example, the rudder cables go through a slot in the SS portion of the
firewall. The rudder cable slots are fairly large (allowing for the
nicopress
sleeve and tails on the thimbles) Are these 'gaping holes' acceptable?
Which of the SS panels are people running their cables and fuel lines
through?
Are regular rubber grommets oK in metal that could reach fairly high
temperatures in the event of an engine fire?
