Hi Mike. I am not at the stage you are but have
talked with Chris Heintz about the tank plumming. He
said it would be no problem treating both tanks in
each wing like one tank. Connect the tanks at the top
and bottom. The only filler and vent is on the
outboard end of the outboard tank. The inboard tank is
sealed - no vent or filler. You can put the fuel
sender guage on either tank depending on the factor of
safety you want. You would still want to put drains
in the lowest point of each though. This will
simplify the plumbing a lot and for now it is what I
plan to do.
I haven't gone through the process far enough to
address your other concerns but this simplification
should help all around.
If this solution is in conflict with some regulation
or other, please let me know list

The only comment I have (similar instalation in diferent plane in our
Club) is that to get both tanks full, will take some time, the gasoline
has to transfer from one tank (out) to the other tank (inner) to get
both of them full, this time will depend directly in the size of the
gasoline tube that conects them.

The problem with this solution is that I have already installed the tanks
in the wings (and installed sending units in both tanks of one wing), and
they are already plumbed per ZAC's XL plans whereby the outboard tank's
fuel line runs through a welded sleeve in the inboard tank. So, I could T
them together, but only after both lines leave the wing. I'm not sure
this would be wise?

The older HDS systems with a tank in the wing locker AND an aux tank in the
leading edge, the two are Teed together and works as one tank per wing.
However, if your tanks are inboard/outboard in the leading edge, because the
wing has positive dihedral (the ob tank is higher), you might not be able to
do this. If your inboard tank has a vent tube or vented cap, then this
would be the limit of how high you could fill the outboard tank in a T'eed
system ... However, if your inboard tank was somehow vented into the top
corner of the outboard tank, then it could work...
With respect to wiring, my routing on the HDS would not work on the XL due
to the different wingroot attachment point....

All,
The numerous "put me on the map, too!" emails without the do not archive tag
have been somewhat disturbing to me.
No one has offered to create a map of builders.
I am exploring the idea of hosting a buiders' database on my web site.
Possibly. Maybe. As in, now's not the time to say, "add me too!"
I am gathering the resources I would need to host such a resource for fellow
builders. At this time, I'm in need of a database that has airport codes
along with the latitude and longitude of the airport. If you can point me
to such a database, I would greatly appreciate it if you could send me a
link off-list.
Otherwise, if and when I create a website for this purpose, I'll let y'all
know.

I'm laying out my instrument panel (winter work in Maine). I know about software
like Panel Planner, but am looking for something like paper cutouts of varous
instruments for now. Does anybody know if such a thing exists?
Thanks for info.

++ Bill,
As a suggestion, Sky Sports has a neat catalog of all kinds of instruments
in full color and full size. They will gladly give you two catalogs which
will allow you to cut one up and save the other one. I laid out my panel
that way and found it great because I could rearrange the layout so quickly
and easily. Incidentally, I bought several instruments from them, fuel
level sensors, and some headphones, and found the quality of the them to be
very nice, and those folks are great to do business with.

Bill,
The Aircraft Spruce catalog has a page or two on the dimensions
you need for each type of instrument with cutouts for the rate of climb
and the sensitive altimeter, etc. Do a layout on the panel directly with
ink marker on a compass and square. Adjust for centerlines. There's
guidance on spacing too.
I must have laid out the final panel and readjusted it 4 or 5 times. I cut
a bunch of
scrap aluminum to set fly-cutter diameter accurately. The cutouts were done
with a piece of masking tape placed over a good cutout template, marked it
and restuck
it on the 45-degree radial for the instrument and marked steps lightly
around it with a punch.
Then cut close with a nibbler, slowly on .065, and filed to the lines. Got
a really
good fit in all. I made templates too, but had to do it on the panel to see
the proportions
for the layout.
Hope this helps,
Larry C. McFarland - 601hds @ http://www.macsmachine.com

Bill:
The Aircraft Spruce catalog, page 365 has the dimensions of the standard
instruments. That's a start, at least.
