What are my options for a fuel line firewall pass through? I will have FI with the AFP pump and want to terminate the cabin fuel line from the pump at the firewall. I have an appropriately sized steel bulkhead fitting - any issues joining aluminum tubing on the cabin side to steel?

Steel fitting

Carl,

No problem with a steel fitting and your alum. tube. This is a safer way to go through the firewall, as the steel wont melt like the alum. fitting would. Will help keep the fire on the other side of the "firewall".
