For those using flexible hoses for the fuel lines what type of hose end fitting did you use at the fuel tank side. I am thinking of using a 60 deg hose end fitting and running the hose so that it has only one bend from the fuselage to the fuel tank.

Thanks

I used 45 degree fittings. Be aware that the fuel line will go
right past the vent tube from the tank. I don't know what would
happen with a different fitting for either hose length or the
way it would run past the vent tube. In my case with 45 degree
fittings it was nice in that the fuel line came up right next
to the vent tube but didn't quite touch it, so it was a very easy
thing to do to squirt in a gob of RTV between the two and create
a nice spot that keeps them separated and chafe free. A different
fitting may make it either much further away or make it try to
run right through the vent tube....but I have no idea for sure.

Niko:

The 60deg fittings won't fit in the tunnel when you mount them to the fuel valve. I bought banjo fittings from Andair www.andair.co.uk, and attached 864 hose ends from A/S (about$15 each). Andair also offers a 90deg fitting that goes on the valve housing, however, I like the flexibility of the banjo fitting better.

Steve, are you flying yet with the Banjo fitting? I wanted to
consider it but the delivery and cost got me wondering, along
with the fear that the flow might not be as good thru
that fitting as a smooth AN elbow on a hose. I am just wondering
if you're seeing any flow related issues like cavitation or
restriction if you're flying. If not, that would be a great
way to hook the valve up too.

Thanks for the reply Steve. I was actually wondering about the other end of the hose, the one that connects to the fuel tank.

Thanks for the info Tim. Did you wait until the wing intallation section to mount the hose end fitting that goes to the fuel tank? I think this way I can ensure that I got the hose length right.

Tim:

Not flying yet. I'am just now installing the fitting, however, they really
look great, and I really can't forsee any cavitation problems, the bend is
very similar to a 90deg fitting. I am installing an Andair duplex fuel
valve to accomodate the return line on the Eggenfellner engine I am
installing, and it is larger than what you "Lycos" install. My engine
arrives in about 6 weeks, and I will install it shortly thereafter, and I
will know more about the fittings then.

Yep, that's what happened that caused me not to use the conductive
teflon lines. Those would be ideal, but I couldn't terminate them
myself. So, I cut the hoses a little long and didn't install the
tank end fittings until I mated the wings to get the proper length.
I tried to make them just a tiny bit long in case I messed up the
end of the hose and had to shorten in 1/4" one or two times
redoing it. It wasn't as fun to do on the plane, but it did
work fine. I probably could have yanked the line and put the
fitting on. But, that's how the length came out right.

Steve,

Finally someone brave enough to talk about an eggenfellner engine.

Are you putting both batteries on the firewall?

Are you using an Andair valve with an extension to keep the fuel line from
climbing up from the bottom of the tunnel or just making arcs in the fuel
line to reach up to the valves' high position.

You have the turbo version correct?

It sure is amazing to see the amount of work Jan did on the web page to help
with install, electrical, motor, prop, etc.

I got a lot of reading to do.

They're all jealous.

Yes

Are you using an Andair valve with an extension to keep the fuel line from
climbing up from the bottom of the tunnel or just making arcs in the fuel
line to reach up to the valves' high position.

I'am installing it high, and letting the fuel pump do it's thing.

You have the turbo version correct?

Yes

It sure is amazing to see the amount of work Jan did on the web page to help
with install, electrical, motor, prop, etc.

You're right. however, I hope we see an update soon with all the changes in
the H-6

I got a lot of reading to do.

Don't we all !

John
I have been talking all along about installing an Eggenfellner engine. I
placed the first order for one for the 10, they used my engine mount and
cowl to develop the engine, and I have readily answered any question
from all about anything I am doing.
The turbo is the only version that is recommended for the 10. The weight
of the firewall forward package, including the 4 blade lightweight prop
is comparable or slightly less than FWF for a Lycoming. The dual
batteries are still being mounted to in the standard Vans location, Jan
makes a battery tray to mount to the firewall in the smaller planes, so
what I did was buy that, cut it in half, welded a plate to the end and
the two batteries fit on the Vans battery tray.
I was down at the Eggenfellner factory last week, and got to see my
engine in final assembly and 55 others. Jan had the Turbo H6, with the 4
blade prop installed on the factory plane, he started the engine and
taxied around, and there is no way to describe the sound, it was so
quiet and when I put my hand on the wind there was little to no
vibration. I can not wait to get this engine flying in a 10. The reason
we did not go flying was that it was after 9 pm and we were both tired.
Now, how many of you can actually say you visited your engine
manufacturer that late at night and were welcomed, even encouraged to
stop by and check it out. We just happened to be in the area, called and
he said stop on by. The support system for this engine is unsurpassed in
my mind. Jan is accessible at all hours of the day, and continually
answers his email and posts to the web 24x7. I often wonder how he does
it. I have the utmost confidence in him and the engine.
If you have any other questions feel free to ask, I am sure many more
people want to know more.

I can sort of visualize what you are describing. A photo or two would be worth
a thousand words! Inquiring minds want to know...

Depending on which valve you are using you can also just come off the
90's using a 45. Here's what I did:

"Are you using an Andair valve with an extension to keep the fuel line
from climbing up from the bottom of the tunnel or just making arcs in
the fuel line to reach up to the valves' high position."

"I'am installing it high, and letting the fuel pump do it's thing."

Restrictions on the low pressure side of EFI fuel pumps have been known
to cause vapor lock. EFI pumps need to be self priming or as close to it
as possible. The regulator bypass that Egg recommends should help with
vapor lock but it also means it will take longer for operating pressure
to be achieved if you run a tank dry. In this condition the auto pump
failover kicks in but it is still trying to suck fuel from an empty
tank. When the pilot switches tanks (how many seconds?) both pumps are
now tiring to suck fuel from the new tank. It will take some time to
prime if the fuel is not already waiting at the valve. How many seconds
will this take? Both these times are unknown. If your on final or climb
out it might be a serious issue.

I am using the extension with the duplex andair valve to keep the pumps
as low as possible in the tunnel. I purchased a Facet pump to assist
with priming but have decided not to install it yet. I think we will
have enough hydraulic head to self prime the pumps if the valve and
pumps are sitting low in the tunnel. It will be March before I can mount
my wings and test. The andair extension is cheep and really looks cool
Smile Just had to move the selector closer to the firewall an inch or so.

FWIW

I always like to hear stories of above and beyond customer service, it
is so rare these days to find vendors willing to go the extra mile for
you, and as RV builders we are lucky to get to deal with so many of
them. We are unique in this situation, I have heard so many "bad"
customer service stories from other kit builders site's, that I am happy
to have chosen Vans and even better that the RV community is so strong
and supportive of each other.
If you guys ever get to NWPA, stop on by, as we are only an hour from
Niagara Falls, and makes for a great flight. We would be happy to take
some southerners out to lunch!
