I need to redo my fuel lines. The current ones got kinks and scratches when I made them. And this is the second set. I've decided to replace them with some steel covered manufactured tubes.
But first I need the forward end of the fuel line established on the firewall.
Turns out there is a drawing OP#32 that shows the firewall for a fuel injected engine. There is this doubler that gets riveted to the firewall and then a normal elbow AN fitting passes thru.
So I made the doubler and located it. I have to remove the rotisserrie, temporarily in order to put this on.
