--> Zenith-List message posted by: "Peter Barthold" <peter.barthold@t-online.de>
Hello Listers,
I thought, I'll ask while the topic is about fuel sending units. I am in the process
of building my own HDS wing tanks. Got the sheet metal clecoed in form and
now it's time to buy components and fittings. Is there any reason why I should
not use a automotive tubular fuel sender instead of the standard floating
lever unit? I expect a better dampening than with a free floating lever. Some
of these tubular senders even have fuel pumps integrated (old BMW 3 series).
I will use mogas on my VW conversion.
Any thoughts?
Carlos, if you read this, did you test your tanks for leakage yet? How did they
come out? Are you going to use mogas?
Thanks and
Best Regards from Germany

Peter, I am ready to test, but haven't had a chance yet.
I haven't decided on the engine, but Jabiru is a possibility.
I understand pro-seal is mogas resistant.

Dr. Ed and Michael:
That's what I did (cut the slot all the way through).
http://www.cooknwithgas.com/3_5_03_SenderParts.JPG
I also made my hole a little oblong (see picture). But
the most important thing about this installation is
the ground. If you look closely you can see where I
tack-welded the arm to the top of the sending unit.
It is critical that the two parts make good contact
and both of my sending units were intermittent even
when bolted tightly together. Mine are the Aircraft
Spruce universal senders (p/n 05-16710).
Good luck,

Peter,
I assume the tubular sender is one with the float
inside the tube? The one thing I can think of that
might be a problem would be that if the sender is not
perfectly vertical, friction may prevent the float
from moving freely. If you get one and do some tests,
it may be a non issue. I agree that the damping would
be better due to the small hole that the fuel column
is flowing through.
Best regards,

Ed--- I had the same problem when I had capacitance probes in my 701. I even put
finger nail polish on the adjustment screws-------- will not be putting them
in my 601 XL-------- this time I am keeping it simple.

Listers -
Is there anything wrong with having the wiring go through the same
lightening holes that the control cables will run through as long as
they are kept to the edge? This would include strobe/nav,
taxi/landing, and aileron trim cables (and probably tubing for an
AOA). Just thought this might be easier than drilling a grommet hole,
but obviously I don't want to interfere with the cables.
Thanks, Michael

i'm just about done with the first wing and discovered their are new
Photo Assembly guides for just about the entire 701 wing. I was at
the rudder workshop when they first appeared but no one mentioned
them. The only other recent change is to the landing gear.
If anyone missed them they are at www.zenithair.com/stolch701/7up-

Michael,
You can always use lightweight PVC conduit to be sure that the wiring
stays
in a safe place. I attached mine to brackets on the ribs with adel
clamps.
The big benefit is that you can postpone the wiring until later in the
build. It's also very easy to change wires without unzipping the wing
skin.

Graham/Michael,
With respect, and wishing to make sure you don't tred on the toes of
officialdom, it may be prudent to check that any applicable fire
ratings for PVC usage are observed. I recall PVC burns with toxic gas
emissions. Other listers may be better aware of any local constraints.
cheers

It was surprising, how much this instrument panel weights.
