Just guessing on Q1 but I think it would work OK in that orientation.

I used 5/16" fuel line on my 231 floscan sensor but it's in automotive EFI rubber type plumbing.

OK, 2 questions.

1. For those using Floscan fuel flow transducers:


Anyone have a floscan 201 sensor that's working ok while mounted in other than a horizontal position? My most convenient location would have the fuel path flowing up at a 45 degree angle. In addition, the mounting can have the wires 'up', but mounting would be a bit more convenient with the wires pointing horizontally.

2. While researching Q1, I found a note from the guy who makes Airflow Performance fuel injection systems for Lycs (they run at around 15-30 psi), recommending 1/4" (AN-4) fuel lines firewall forward to minimize fuel heating & vapor lock. I've already been tempted to consider this instead of -6 (saves weight, running lines is easier, etc) because the injection pumps & automotive systems use small diameter lines, but was reluctant to go against 'convention'. Has anyone who's flying an injected rotary used -4 fuel lines to feed the engine?

Thanks,

Charlie
