Mike,
I also put the rudder cables into conduit from the firewall to the pullies.
That way you don't have to worry about any rubbing anywhere. You can redux
them to the front and back areas.

A handy chart I have rates metals from anodic (top) to cathodic (bottom) as
follows:
Magnesium
Zinc
Aluminum alloys
Cadmium
Steel
Lead
Chromium
Brass/bronze
Copper
Stainless steel
Silver
Nickel
Graphite composite
Cadmium plated AN hardware is very near aluminum alloy and not coincidental it
is so plated. Stainless steel is further apart from aluminum than brass, but
I've yet to notice serious corrosion after many years of intimate contact.
Ditto for aluminum fittings on steel elbows, which should be steel if attached
to a vibrating engine. It's really just a maintenance issue, since in enough
years it may leak or be damaged if disconnected.
Regards,
Fred F.

For Part !, the short answer is: don't worry about it.
The slightly longer answer is: in order for corrosion to occur there must be
an electrolyte present in addition to the dissimilar metals. On the fuel
side, barring the presence of water in the fuel, there is no electrolyte
(gasoline and Jet A being non-ionic liquids) so there is little risk of
corrosion. On the exterior, where moisture laden air can be the
electrolyte, corrosion may occur, but it will not do much damage and
certainly won't do any damage quickly. A visual check during the annual
inspection will confirm that neither the fittings nor the pump is
dissolving. In this combination, Al vs. Cu, the Al will "protect" the Cu
from corrosion (meaning that the Al will be attacked, not the Cu), just as
Sir Humphrey Davy's innovative use of iron anodes protected His Majesty's
copper-clad ship hulls from corrosion beginning in the early 19th Century.

For Part 2, the rudder cables run UNDER the pulleys.

For the experts in this field......Would there be a dissimilar metals
problem
if I used brass fittings along with my aluminum ones in the fuel system?
And I am running these fuel lines and want to avoid an interference problem
later on with the rudder cables running down the center of the cockpit
module.
Does the cable from the rudder pedals run under the pulley between the
pulley
and the bottom skin or on top of the pulley between the pulley and those two
small inspection holes next to the seats?

Thanks to all for the help. This Forum is worth the $ we all put into it. I
posed these questions last night before bed and when I wake up I have the
answers to continue to work. At this rate I'll never have any time to catch up
on
the latest movies. ;-)

--> Europa-List message posted by: "Steven B. Janicki" <longezav8r@yahoo.com>
Hello,
I have a airpark lot located at Lake California 68CA, www.lakecalifornia.com that I would like to sell/trade for a Europa XS Tri-Gear kit (preferably fast build options and little to no work completed). My lot is valued at $35k which is the equivalent to a XS Tri-Gear with fast build options. Lake California is a gated community located just south of Redding California.
Please see the above web site for full details on the airpark and community and
send me an e-mail directly if you have further questions.
Regards,
Steven

Steven

Paul, I have the EIS and you need two transducers, one for the fuel in and
fuel out. Grand Rapids will set up your unit to properly measure the
difference. It takes a little time to calibrate but is very accurate.
