Hi Marcos,
I have a Zodiac XL, so I am not sure how much my experience will help
you. Perhaps you would like to find someone who has one of these and
look at the drawings.
On the XL there is an aluminum tank in each wing. The tanks are placed
in the nose area and supported by cork strips all around the tank. The
tanks are not connected to the spars. Several nose ribs are removed and
other support devices which look like "V" shaped aluminum strips
installed. There are holes in the inner three nose ribs to allow for
the fuel lines to go to the fuselage. Other holes include one in the
top for fuel filling and one in the bottom for a very neat vent system
that seems to work very well.
Each tank has a finger strainer to keep big junk out of the fuel lines
and an electric sender to detect fuel level. Some builders build access
ports for the fuel senders, but I have not done that. Senders can be
installed on tank top or inner wall. I chose the top fearing real
problems if a leak develops. Sender installation is a little
complicated because the tanks are insulated from aircraft electrical
ground and a ground must be added for them to work.
Good luck,
Paul

Hello, Marcos
Plans are available from ZAC.
Paul's description of the XL arrangement also applies to the HD.
If you do not want to weld, I suggest you research the method used by RV
builders.

Hi Marcos,
I built tanks within my wing leading edges. It was and interesting
process.
The process is documented in Section 2 of my journal and in subjects of
construct in the site menu called =93lead edge tanks=94. See my website
at
macsmachine.com. The pictures show tools, jigs and some of the
methods which enabled fitting, jigging and welding the ends, back and
nose
skins. I=92d recommend you use .032 minimum material if you are welding
these.
You could possibly do without the drawings if you look very carefully
at
what was done on my site and template tank ribs 1/8 inch smaller than
the
wing
ribs and shorter by the depth of spar bumpers. Also, it=92s not hard to
make
a set of filler caps that go flush with the wing skin if you study what
was
done on my site.
I will say that the constant chord non-tapered wing should make the job
much
easier than what I had to do with the HDS.

Hi Marcos,
Yes, there are no holding points or fasteners per se, but the fit has to
be such that the nose skin, spar bumpers only contact the cork that gets
wrapped
Around the tank. The tank should fit like a glove and it will not move
about at all after the nose skin is formally clecoed or riveted in
place.
.040 is a bit heavier than I=99d use for wing tanks. .040 would
weld fine, but it=99d be 25% heavier than it should be and not
improved for strength or durability.
Not so sure of the tank length, but the clearance was approximately
=C2=BD inch tank end to rib each end.
The first half of Journal section 2 covers most of the process of doing
tanks.
Good luck!

I have an idea of what I need but just some points of doubt:
- I understood thast there is no fixing points, just the cork and the

- What about the angles on the rear (between tank and spar) Is only to
separate a little, no rivets or screws to attach the tank?
- How long is the tank and how much separate from the first rib?
I read about using 5052 aluminium sheet, but I have a lot of 6061T6
sheet of .040 but i=C2=B4m not sure if this is weldable.
