Have you perhaps forgotten that all small Cessnas -- BTW, a
"Certified aircraft manufacturer" -- have gravity-fed fuel systems?
Backed up sometimes by both mechanical and electrical fuel pumps.
And for how many decades has this been working just fine?
On Cessnas, Stinsons, Taylorcraft, Luscombes, Norsemen, Otters.
Beavers, etc etc.
Perhaps no one ever told Clyde Cessna that it wasn't a good idea.

The system should be designed so that either pump alone could keep the
engine running. Chances of having two pumps fail at once are nil, and you
don't have all the hazards, and complication of what you are proposing.
Tank above, tube in the middle, carburettor below. No pump. What is
complicated.?

JSwan,
What you describe above is a very reliable, well thought out, and still simple
fuel system.
Electric pump to push fuel up to the engines pulse pump - All pressure fed, Never
draw fuel for any distance with a vacuum.
Gascolator
Quality Fuel Line
Quality Filter
A high quality, simple, and well engineered fuel system can easily be done on even
the smallest ultralights that use a Rotax 447 ( Firefly )... Something as
simple as a well designed fuel system would eliminate a large percentage of
Kolb engine failures. In ultralights we cant always have the same safety standards
as full scale aircraft, its not always practical for an ultralight...
But the fuel system is one area that can be designed to aviation standards and
still be small, simple, light and still practical for an ultralight. I don't
subscribe to the attitude that some people do, that just because they am flying
an ultralight, that they will use cheap and substandard parts, and poor
engineering practices. I build and maintain my planes, even the small 2 cycle
planes, as close to accepted aviation standards as possible, and to be as safe
and as reliable as is possible as technology allows in an ultralight.

Russ and Dana,
I never said that a gravity fed system was not a good idea... I said that running
fuel tubing from the bottom tanks of a Kolb to an EXTRA tank on top of the
engine on a Kolb as Dana described is a bad idea, and most definitely an added
fire hazard.
Dana's other configuration idea, which is to mount the main fuel tank on a Kolb
above the level of the engine is also just as hazardous, draggy, and not practical
in an aircraft where the engine is the highest part of the plane.
Both these scenarios are very different from having gravity fed wing tanks in a
Cessna. I personally thing these two individuals are just looking for any way
possible to discredit anything I post here, even if they know they are being
dishonest in their comparisons and conclusions. If these two individuals honestly
did not understand these basic concepts, and posted these bad comparisons
in error, they certainly are not qualified to be giving technical advice on
airplanes. Either way makes them very non credible posters.

Scott,
I used an UltraStart-Red battery for starting the Victor 1+. It is a little
expensive. The first one lasted 468 flights from March 30, 2002 to July 4,
2008. I am on the second battery, and it is not doing well. After 52
flights the battery will not hold a charge well. I keep a booster on the
battery to keep it fully charged in the hangar.
This battery can be purchased at Aircraft Spruce for about $90.
How it was mounted can be seen at:

Subject: Kolb-List: Poly-Fiber Reducer substitute?
25oct09
Kolbsters,
For the past year and a half I've been stuck on Oahu. Back on Maui my poor
ireFly has been sitting in a field in the Hawaiian Home Lands. She was fol
ded,
n her trailer and covered with tarps. I placed desiccants in the intake an
d
xhaust. But it's still going to be a job to get her airworthy again.
At the top of the list is to repair an 11" tear on the top of the port win
g. I
ave never worked with fabric. I tried to buy the Poly Fiber practice kit
ecause (besides needing to practice), I figured it would have all the supp
lies
eeded to patch the wing. All the suppliers (the usual suspects) I contacte
d
equired $300+ to cover the HAZ-MAT for the flight to paradise. I called
oly-Fiber and they said they didn't have a distributor in Hawaii.
Luckily (?), I inherited the remains of the supplies used to cover the pla
ne in
997...
There is a jar marked Poly-Tack. It's slow moving but crystal clear, so I
figure
little MEK will loosen it up and it will be OK...
I have a small can of Poly-Brush that feels almost full. Also, there is a
half
ull large can of Poly-Spray. Both Poly-Brush and Poly-Spray require
oly-Reducer... I have no Poly-Fiber Reducer...
Question number 1... Is there a chemical, that I can obtain locally (Hawai
i),
hat can be substituted for the Poly-Fiber Reducer?
For color, there are two small cans of Poly-Tone, about a quarter full. I
read
hat it may be reduced with MEK... No problem.
There is plenty of Poly-Fiber 1.6 oz. fabric to make the patch. But I have
no
ape.
Question number 2... May I cut my own tape from the 1.6 oz. Poly-Fiber fab
ric?
Any information or hints on this subject would be most appreciated. Thanks
,
head of time...
Not finding what you want, living out of catalogs, making do and finding
ubstitutes is all part of living at the far end of the technical food chai
n...

Obviously you didn't bother to read my entire message. I fly an UltraStar,
which has the engine BELOW the wing, with plenty of room for a tank above
the engine. I wasn't proposing it for any other Kolb model. I'm not so
stupid as to think that it would make sense for an aircraft with the engine
at the highest point.

Subject: | Re: fuel system debate |
Jim, It's the beauty of experimental aviation that a builder has the right
to design his system as he sees the requirements. I'd love to have a nice
light weight aluminum tank with bungs for bottom draw and water drains, but
for now I have plastic tanks with TNK supplied top draw fittings. I've had a
broken off flapper valve in a primer bulb put me on the ground and found a
split bushing on a bottom tap so I learned from those failures. Realizing
the danger of no longer having a balance line between tanks I put in a
selector valve so I can draw off left or right tank, or both. I can also
shut off the fuel draw completely should that need arise. I put in a Facet
low pressure pump as a boost pump, but I have a Mikuni pulse pump, too. I
know from testing I can shut off the boost pump and the 582 hums right along
on the pulse pump alone. The only problem I've had was caused by plastic
debris from a gas can mod that jammed the selector valve. Now I have pick up
filters to keep that from happening again. The experiment continues and I'll
adapt the system as I see fit. The choices I've made have been driven by the
experience of myself and others.
All these absolutes about must haves and must bes are just so much
belligerent chest beating.
Bottom line is, and this isn't directed at you personally Jim, if YOU want
the best system for YOUR airplane sit down with pencil and paper and start
with YOUR ideas and build the system YOU want. Make YOUR best decisions,
take pride in and do YOUR best workmanship, test YOUR system and then, I
hope, put up pictures and descriptions on this forum so we can share in YOUR
creativity.
I continue to learn a lot here from all the builders who graciously share
with everyone. I've never learned a damn thing from the bile spewing of a
guy who never shares anything but his bad manners.

for now I have plastic tanks with TNK supplied top draw fittings. I've had
a broken off flapper valve in a primer bulb put me on the ground and found
a split bushing on a bottom tap so I learned from those failures.
Realizing the danger of no longer having a balance line between tanks I put in
a
selector valve so I can draw off left or right tank, or both. I can also shut
off the fuel draw completely should that need arise. I put in a Facet low
pressure pump as a boost pump, but I have a Mikuni pulse pump, too. I know
from testing I can shut off the boost pump and the 582 hums right along on
the pulse pump alone. The only problem I've had was caused by plastic
debris from a gas can mod that jammed the selector valve. Now I have pick up
filters to keep that from happening again. The experiment continues and I'll
adapt the system as I see fit. The choices I've made have been driven by the
experience of myself and others.
All these absolutes about must haves and must bes are just so much
belligerent chest beating.
Bottom line is, and this isn't directed at you personally Jim, if YOU want
the best system for YOUR airplane sit down with pencil and paper and start
with YOUR ideas and build the system YOU want. Make YOUR best decisions,
take pride in and do YOUR best workmanship, test YOUR system and then, I
hope, put up pictures and descriptions on this forum so we can share in YOUR
creativity.
I continue to learn a lot here from all the builders who graciously share
with everyone. I've never learned a damn thing from the bile spewing of a
guy who never shares anything but his bad manners.

Hi Rick,
I take no offense from your post...I agree with your dual system....I
like the idea of people posting pictures and drawings of their system's so
it can help people make good decisions.......my firestar had plastic tanks
when we got it and fuel oulets out of the bottom....so we just left it that
way. I put in a elec pump which is below the tanks....if the elec pump
will pull gas using top tank fuel lines i see no problem with it.I know a lot
of people do not like the idea of those rubber groumets in the bottom of
the plastic tanks but i have had no problem with them so far....they did leak
a bit when we flew the plane back to Michigan from Oklahoma but i replaced
them and they have given no problem since. The mikunni pulse pump is
drawing gas almost to its maximum distance specs in most all of our kolbs where
the two plastic fuel tanks are used and located, and yes things must be
maintained.. I do not want to beat this fuel system thing to death but feel
it is important, do not like to have people get hurt. I know some of you
guys fly over terrain that I would feel uncomfortable in a twin...jswan

Subject: | Re: FireFly - MZ 34 Start Up |
What type of booster are you using to keep your battery up. I've
heard from some people that ones Harbor Freight sell will do your
battery in after a short time. Same I told the ones that Batteries
Plus sell are better. I have got the foggiest idea which is
better. Any one got any factual info on this subject why one is good
and the other is bad?

Subject: | Re: Poly-Fiber Reducer substitute?- Cutting Fabric |
Using pinking shears can be a challenge, I got Fiskars and also the
expensive ones Aircraft Spruce sells. If you need to cut much get a
Fiskars rotary cutter and mat. The cutter resembles a rotary pizza
cutter available in straight and jagged edge. Man you can cut Dacron
fabric like there is nothing to it. You can do curves, circles,
etc. Great for cutting circle pieces for covering the plastic
inspection holes reinforcements. A great Christmas gift for your
wife if she sews much.
If you need a lot of tape for seams, it's probably just plain easier
to buy it, get the bias type tape if your going around curves like
corners of control surfaces like rudder or elevator.

Thanks Guys...
I heard from David Starbuck (some of you know him from his days at Kolb), he also
thinks that lacquer thinner should work.
Got my pinking shears... On-ward & up-ward.
Ya gotta love this list...
