Everyone using this for fuel lines should consider this. Non-conductive PTFE can build a static charge when used with fuel, potentially causing a discharge that could lead to dangerous situations. An engine fire would be a disaster.
I’ve got some thoughts on PTFE fuel hoses…
Teflon is far more suitable for fuel applications, but it’s important to have a generous bend radius with EVIL PTFE. Using a conductive PTFE formula would help prevent micro-arcing from the fuel to the braids over long runs. Otherwise, EVIL remains the best affordable option.
