Thanks guys. I just called several hose manufacturers, including Fragola, and what they told me was pretty interesting. All of the tech guys I talked to said they've never heard of a specific incident where non-conductive hose caused a static discharge or an issue otherwise. According to them, it's a bit of a non-issue. And this was coming from hose companies who sell the stuff. I know I've run non-conductive ptfe for years in various cars and have never had an issue.
Do you guys use conductive ptfe? If so, from which manufacturer?
