Inside the cabin I’m using aluminum fuel lines. I’m also using limited aluminum fuel lines on the outside of the firewall. After the fuel filter is where I will switch to use teflon fuel lines that run to the engine.
I’m also wrapping the fuel lines insulation in heat resistant aluminum tape. The picture below shows an aluminum line half wrapped in insulation and half wrapped in foil tape, for the purpose of illustration only. I’m kind of paranoid about vapor lock so I’m trying to do everything I can to resist heat in the fuel lines. I also went out of the way to keep the lines as low as possible as long as possible.
I know this is far from standard, so please feel free to comment and tell me all the ways I’m doing it wrong.
