Hello, Marcos
I believe the valve and fuel line specs are regulated locally.
I didn't do the plumbing yet, but I recall having read posts saying that in
Canada we need at least 3/8" (if memory serves me). There is also some
restriction on the fuel valve (I think it cannot (or must??) have a "both"
position...).
I suggest you talk to local builders to see what is required.
Good luck
Carlos

Hi Marcos,
Both on fuel selector only works for high wing aircraft.
If you want to learn why, get two glasses of water and two straws. Put
only a little water in one glass and fill the other one. Then suck on
both straws together. What will happen is you will empty one glass and
then just suck air without ever getting any more from the full one.

Subject: | CH601HD Wing tanks |
HI Marcos,
You=99ll be better off using 3/8 O.D.- .035 wall 3000 series
aluminum fuel line. The 3/8 line has been nearly a requirement in
aviation for a long time. Select only a fuel valve that allows left,
right or off.
6061 T6 is also easily by TIG process. 5052 is selected for deep formed
products that need to stretch. 6061 is very corrosion resistant and
suitable for tank material.
Try to get something like an Andair fuel valve, with left right and off,
see FS20 valves at Aircraft Spruce.

Hello Larry and all,

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!

Hello Larry and all,
Thanks a lot for your help, I=C2=B4ve studied your web several

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
wing skin around it?
- 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.

Hi Marcos,
I built tanks within my wing leading edges. It was and interesting

subjects of

my website at macsmachine.com. The pictures show tools, jigs and some of

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=99s 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.
