Hi Charlie,
Ok, I found a web site that had a chemical pump pushing 39
gallon/hour through a 1/8-1/4" ID line - it didn't state the pump pressure, but
I doubt it was as high as an EFI fuel pump. Looks like 1/4" should be no
problem. Just wanted to make certain that deviating from the tried
and true was not going to get you in a pickle {:>)

Hi Ed,
I think that my 1st attempt at a reply disappeared
in a power outage here in MS.
I re-checked the post on VAF, & he
definitely said -4 pre & post sensor. The lines from the dist. spider to
injectors on the a/c systems are much smaller; probably 1/8-3/16" OD. The actual
ID is really small (I had a Precision brand system in my possession for a while,
during my Lyc detour).

Charlie, were these lines recommended for 1/4" dia SS
tube - the lines from the air performance fuel distribution block to each
injector or from the tanks to the fuel distribution block? Makes a
difference. 1/4" dia SS tube would have no problem providing fuel for
one injector - but, I would make certain which lines he is referring
to.

Subject: [FlyRotary] Floscan orientation, fuel line
size
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
