At first I was thinking there wasn't much difference between -4 lines and the 5/16 I was using but on second thought, -4 is only 3/16 ID compared to my 5/16 ID which is a big cross sectional difference. I am flowing 30 GPH at full power and rich mixture though which is 50% more than a 13B would.

Thanks, Tracy. My pumps and the regulator are on the floor between
spar & firewall (RV-7), & it's an easy path up the diagonal
brace on the firewall, with the sensor at roughly mid point. A
second look a the firewall, & the angle is closer to 60 degrees
(measured it:55*). This spot may not work anyway; it's looking like
rudder pedals may hit it or the fuel line if run there.
I think I'll take a closer look at -4 lines, though.

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

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
