Fuel Lines
Parts Tips:
Be sure that before you get to the fuel line section you
have
purchased your fuel flow transducer (Ususally included with your
EIS), your ES Airflow fuel pump, and ES Airflow fuel filter.
You need all of these items to complete the fuel lines. The
fuel flow transducer and EIS may very likely have many weeks of lead
time, so probably try to choose your instruments and EIS in particular
at the very beginning of the fuselage section.
Parts Shortage??
I'm not sure yet if I'm short these parts, but, the fuselage kit only
contains 6 of the MS21919WDG6 Adel clamps. 4 are required for
fuel lines on pg. 37-3, 2 on 38-10 Rudder cable front exit area, and 2
on 38-8 Rudder cable rear rudder cable exit area. I still had 2
from my empennage kit, so perhaps these were for the rear rudder cable
areas. I'm not sure if I'm short yet or not. If I were you,
I'd order a couple spares.
Andair
valve vs. El-Cheapo Van's valve
Ok, so I'll complain for a minute, but don't get me wrong, I think the Andair valve is great....just
DON'T ORDER ONE FROM WICKS!!
I originally ordered one from Van's, but it was backordered for a few
*weeks*. Then I found Wicks had one, so I dropped my Backorder
and got one from Wicks. Turns out this isn't the same valve.
What you WANT is the FS20x3-F, with 1/4" Female NPT pipe
fittings on the left and right tank fittings. Wicks sells the
FS20x3-M, with male flare 3/8" tubing fittings. The RV-10 doesn't
have enough room in the tunnel to mount the male fitting valve in it's
original (and easiest/nicest) location. I got the valve from
Wicks. When I realized that I was in a bind, I first tried the
expensive ($55+) step of ordering a Banjo (moveable elbow) fitting
(Andair specific) from Wicks...the F20B. Unfortunately they were
out of stock. So, finding a Banjo fitting at Aircraft Spruce, I
had them verify that it had 3/8" tubing on the elbow outer end (as I
needed) and ordered it. While in transit, I removed the old
fitting from the Andair valve.....doing this is no problem...just a #9
Torx driver is needed. But, I scratched the valve a bit...no big
deal, but now it's probably non-returnable. When the ACS banjo
fitting arrived, it had a MALE NPT fitting on the inside of it!!! This
isn't right...it needs the 4 screwed flange that it MADE for the andair
valve. Besides that, the web page listed it as Female. Very
strange. So, I had to return that useless piece of junk.
Now I'm stuck trying to get a replacement side fitting for the andair
valve, with no luck. I've REPEATEDLY emailed Andair about these
fittings, with absolutely no reply. I even CALLED England and
left a message and still no reply.
Today I gave up and I bought a 2nd
Andair valve from Van's, I'll use it for fitting my fuel lines, and
then get new side fittings at
OSH. If you're interested in buying my 2nd Andair valve (the
brand new one) after I'm done fitting my fuel lines, let me know and
after OSH I'll sell it to you at a little break off from it's cost.
Reasons for
going Andair?
1) The
standard valve is very ugly.
2) The andair valve has that engraved plate with left/right
labeling
whereas you have to stick or paint on
labels with the other.
3) The andair valve has a more positive detent feel for when you
get
to the left or right position.
4) The andair valve has an OFF position that you can't get to by
just twisting the valve...you couldn't
do it by accident.
I'll be flying with kids on 95% of my
flights, and they
like to climb around and trade seats.
5) It's not really a retrofit difficulty...you have to build the
whole fuel line system anyway. The
convolution is in the
STANDARD valve...you have to cross the
fuel lines so the
Left line feeds the RIGH side of the
valve, and vice versa.
This is an incredibly screwed up
situation, which has already
led to one other builder mounting hsi
standard valve backwards
just to make the convoluted routing
simpler. The Andair valve
is a much more straightforward and
logical plumbing job.
6) The plane is going to be > $150K....point #1 is just too
much
to bear when the andair looks so
nice. I'm not building a
flying lawn tractor.
Below are the initial pics of fitting my fuel lines.
The Left line is just started. The thing on the right is a
piece of plastic tubing I'm using just to get the general shape
pictured so that I can pre-bend the aluminum tube and have it fairly
close. You can also see my mounted fuel pump and filter....still
awaiting my flow transducer.
