| Subject: | fuel line bubbles-Follow up |
--> Kolb-List message posted by: Ron Hoyt <rrhoyt@ieee.org>
A couple of weeks ago I inquired about fuel line bubbles. I got some
good perspective from the list.
I reviewed the Rotax service bulletin on 912F fuel pumps and
determined that the fuel pump met the inspection test and the
pressure test. The fuel lines, filled with fuel, maintained a 5 psi
pressure for half an hour after pressurizing. (No additional
pressurization after the initial pumping.) I replaced the fuel line
riser section with clear tubing and watched the engines pump draw
fuel without bubbles. The fuel had small bubbles at the input to the
carburetor. They appeared to be the result of trapped air in the
clear tube connection to the fuel system.
I never did a vacuum test. It might have exposed the failure
mode. By replacing the riser section with aluminum tubing and short
flexible couplings to the pump and off the engine to the plane I
seemed to have remove the preponderance of the bubbles. In the
process of removing the neoprene tubing from the fuel pump I found
that it could be turned and pulled off without loosening the
clamp. It did not leak during the pressure testing, however!
I concluded that The neoprene tubing was collapsing and or air was
being drawn in through the loose clamp due to the vacuum exacerbated
by the collapsed tubing.
The plane flew today without flashing alarms. The nominal fuel
pressure was greater than 4 psi and never lower.
I'm posting this follow up for anybody in the future who discovers
bubbles in their fuel line.
Thanks for the help
Ron

Hey John H.
Speaking of nuts, does size (prop) matter. You said your runing a 72" on
your 912S I'll be using a 70" Warp Drive with a 912ul. Is that a good combo
to start with.

Hey Denny...your right about McMaster-Carr. Funny story....my office
used to be in Phenix City, Al. (approx. 1.5 hours southwest of Atlanta,
Ga.)
I called in an order about noon for a couple of things I needed and went
back to working at my desk...'bout 3 oclock the doorbell rings and it is
a delivery guy. This is an everyday thing (getting a package...work
related at least) but when I look at the "from who" on the package it
was McMaster! I asked the guy how it got here the same day and he
grinned and said. "I drove it down from Atlanta!"
Turns out one of their main warehouses is in Atlanta and they do enough
business in my area to run a delivery route direct from their warehouse!
Was the fastest delivery ever for me...

I have never yet found a store-bought clamp that I thought was worth a
flip on clear tubing.
If you are using clear tubing, then make your own fuel line clamps from
safety wire.
Here is how to do it:

I have removed my factory designed trim and installed an elevator
trim. The reason for this was that the factory design trim provided
positive feedback to the elevator control and that results in
negative long term pitch stability. The plane flies hands off the
stick these days.
I also added an aileron trim to compensate for passenger and fuel
imbalance. I have counter balances on these control surfaces.

Mc Master-Carr is an excellent company and should be able to send
you most anything you want. If you have any trouble getting cotter-
rings, most marine-supply stores now have them, in stainless.
I'm curious as to how it took everyone a hundred years or so to
invent them!

For what it is worth, I blew a break line on my MarkIII when revving
up the 912.
I have 6 inch Maco breaks with the factory supplied plastic
tubing. The failure occurred at the tubing connection with the
master cylinder. The tubbing pulled out of the brass connector. The
tubing had compression ridges in it from the clamping action of the
connector. It was in tight. It also had a brass insert to prevent
the tub from collapsing.
I phoned the Maco factory and discovered that the breaks were too
small for the plane and engine. I was putting much more pressure on
the breaks than they were designed for. I had to upgrade the brak
calipers to a larger pad.

Is this true? Will installing a little brass ferrule on the Nylo-Seal
fittings make them work better?
The instructions that come with the Nylo-Seal fittings simply tell you to
"Insert the tube into the fitting and tighten 2-1/2 turns."
I may try it, if the consensus suggests that mixing and matching parts like
this really works.

Don't use them on airplanes!
I've got an F-27 sailboat and the email forum for these trimarans has
reported several instances of the rings coming out. I've caught a couple
just before they came undone on my own boat.
When I do use them, I wrap rigging tape (vinyl tape is fine) around the ring
and the pin that the ring is holding and that whole joint. Then it's an easy
inspection of the tape, which I generally change every time I launch the
boat, once or twice a year. When the tape is wrapped around them they are
fine.
But to reiterate, it's not an aircraft device... far too dangerous.

Looking for more performance.
I believe climb performance is better, but I could not see any
improvement in cruise.
The 72" prop on my MKIII did make more noise than the 70".
Heard there was a modification from Warp for rounding the tips, or
something to that effect. I have not pursued it, but intend to.
Always looking for ways to make things work a little better and
quieter.

At Ralph Burlingame's recommendation, I bought some stainless steel safety
rings at the local sailboat store. They are one inch in diameter, and have
an offset end to make them easy to thread into the hole in the clevis pin.
And as John H suggests, I do not use a clevis pin for the tail wires - I use
an AN-3 bolt with a drilled shank. After I install this bolt with a
wingnut, it is secured with a safety pin (or ring).

Maybe some of the experts on the List will respond to this. I know
Old Kolb and probably New Kolb send along a wing nut for attachment of
the lower wire brace. The bolt is in shear and tension. I have not
checked, but would guess the wing nut is a tension only piece of
hardware. Might be worth checking out. That is why I use a nyloc nut
on the bottom wire brace bolt.

Ah Richard, your site is a veritable garden of fruitful wisdom and I have
always enjoyed your one liner: "ask me how I know this". The wire wrap is a
natural and is far better than a hose clamp as the wire goes in-between the
barbs where the hose clamp simply straddles the barbs. But that homemade
gasolater looks to be a considerable amount of work. But having more time
than money myself, I may give this greater consideration. Do you have a part
number for the filter? Thanks for the info.

Always!
Been flying with nothing but Warp Drive on my MKIII since Sep 1993.
Warp Drive takes a licking and keeps on ticking. Several times the
Warp Drive has gotten me home an incident with FOD that would have
left others stranded without a prop.
Virtually no maintenance. Never had to balance one. It is set and
forget, once you get it dialed in where you want it. A good warranty
for life. If for some reason you aren't happy, call Daryl at Warp
Drive and get a refund.
Not only are Warp Drive props used on aircraft, but on many air boats
which live in an environment that is not nearly as comfortable as what
we enjoy in the air. There is an airboat owned and operated by
Alabama Power Company, powered with a 350 Chevy turning a 6 or 8 blade
Warp Drive. Heard it coming down the lake where I live long before I
discovered what was making all the "Warp Drive" sound.
All 3.5 flights to Alaska by my MKIII were pushed along by a Warp
Drive.
Daryl, president of the factory, is also the guy you will talk to when
you call them on their 1-800-833-9357. He is extremely knowledgeable
of his product and its applications.

Richard,
For those who have not yet used safety wire for hose clamps.
I've used safety wire to clamp hoses like this too, and it works fine
if done right, per your suggestion. The first time I did it, the wire
cut the hose because the safety wire was too thin, so I recommend using
heavier rather than lighter safety wire, as your pictures show. The
thicker wire is less prone to cutting into the tubing.

Can I get an opinion on the Warp Drive Composite from someone using one or

It sure has a purty hub, all engine turned and shiny, but I haven't flown
with it yet. Its in my leather lounge chair in the den. I was a little
disapointed with the workmanship on the instalation of the nickel edges. I
was told it didn't matter, and I am a little anal anyway!

While not an expert, (unknown drip under pressure) I have the setup
described by John. The wing nut holds the wires under tension and then a
clip is put into a hole in the bolt. The bolt is put in from the left side,
therefore everything brushing the wing nut will tighten rather than loosen.
Of course I haven't taxied in too many Alaskan Willows either.

I have a question as well. The gascolater looks to be pretty simple and
ingenious, but I was wondering about the method of attachment to the bottom
of the plane. The L shaped aluminum fitting that goes into the bottom of the
gascolater through the gasket is my point of confusion. I am guessing that
they only make them in that configuration, but it seems to complicate the
fitting to the plane. If you could elaborate on the attachment to the plane
it would help me a great deal. Is the gascolater fastened solidly or
floating with a tube going to the drain arrangement? The fitting that opens
the gascolater to drain, is that just a petcock arrangement, or is it a
standard fuel drain as in G.A.?

| Thanks John,
| Can you tell me if you have any leading edge protection?
Yes Sir.
Warp Drive has a nickle steel inlaid leading edge that is 15" long on
the 72" props. This edge is tough and keeps the rain from eroding the
leading edge of the solid carbon fiber blades. Works a little better
than SS and urethane tape.

Folks,
If the proper size and type hose clamp is used for the application,
the hose clamp will work much better than safety wire.
SS hose clamps come in different diameters, but they also come in
different width bands. Doesn't take a whole lot to properly clamp a
hose is it is done correctly.

The fittings I used on my Matco heel brakes have the brass insert molded
right into the brass fittings, the brake lines slide over the inner tube and
inside the outer one, than the plastic ferrel is run into it with the
knurled nut. I bet these are a lot better fittings than the ones you have to
insert the tube into the line.

Gotta agree with John. I get nervous thinking about using safety wire on plastic
hose. Pick your clamp carefully to size and width as J. says and you will never
have a problem. Don't go to Wal mart and a limited selection. Go to a large
hardware or a major Auto Supply house and you should find the exact number
needed.

Kolbers,
To save weight, I use Richard's safety wire clamps on all fuel line
connections. In my case I put on two clamps side be side, so that if one
fails there is a second clamp. The trick is to twist the wire until the
safety wire has about one half the wire thickness pressed into the tubing.
So far, I have not had one fail.

If fastidiously (hoo boy, got by spel chek) done, safety wire will do
a safe
clamp job. Spiral clamps are a whole lot easier, especially if you
want to
disconnect the joint with any frequency. Go to the plumbing dept at
Lowes.
They have the narrow band type in "all stainless". The cheaper ones
have a plated worm that may rust. I replace my throw-away gas filter
from
Auto Zone every year. Two clamps.

You are too kind. Unfortunately, I do not have a part number, the one in
the pictures was chosen by going to the rotating rack at Advance Auto
Parts, twirled it until I saw one that looked good, and said
"Hmm - wonder if this one will work?" It took about 40 minutes to do.
Sorry not to be more help.

Actually, that gascolator is something I made to use, and then ended up
not using it because I installed a different gas tank instead, (with a
built in water sump to a drain) but I can tell you how I would have done
it, and based on what I am currently using it which has a quick drain-
Since the gascolator is not heavy you can probably stick it in the fuel
line at any convenient low point. The L shaped fitting that exits the
bottom of the gascolator is then plumbed via a flex tube of almost any
description to a low point and then add in a standard GA drain valve.
(SAF-AIR, Curtis Push-N"-Twist, etc.)You can also thread the drain valve
into a standard brass fitting (auto parts store) and solder the fitting
to a short 1/4' copper tube which makes it easier to attach to the
airframe and to the flex line coming from the gascolator.

If you are talking about using hose clamps on rubber fuel line then you
are correct.
If you are talking about using hose clamps on urethane fuel line tubing,
then I disagree. Hose clamps will not work better.
The worm gear hose clamp will always have a portion of the clamping arc
that does not properly conform to the rigid tube that the clear urethane
tubing is being clamped to. Even the smallest worm gear hose clamps are
designed for fuel tubing fittings larger than the 1/4" size that is
commonly used on many Rotax fuel systems. This is an inherent design
flaw of a worm gear hose clamp.
I just came back from the garage where I have a box full of hose clamps
that came off my Kolb. Some of the say "TRIDON", some them have no name,
and some say "MEXICO." Slipped them over a fresh length of 1/4" yellow
Tygon fuel line and ran them down until they just got snug, slipped them
off and looked at them. None of them are round, they all want to deform.
All of them have about 20% of their arc that is the wrong diameter arc,
that is where the worm gear is. On a larger diameter fuel line, they
would not do this as badly. But on a 1/4" fuel line, they distort badly.
Stainless safety wire is the best way to secure clear (or colored - ie
Tygon) fuel tubing. As Jack Hart points out in his post on the topic, it
is easy enough to add more than one wire wrap per fitting, as some
fittings have several barbs, and having a separate wire wrap per barb
becomes totally fail safe.
One final note - Good quality black rubber fuel line lasts longest. And
works well with hose clamps. If you use clear fuel tubing, use only use
clear urethane fuel tubing, or tygon fuel tubing, or fuel tubing sold as
such by reputable u/l dealers. Using clear vinyl or plastic tubing sold
in hardware stores is a good way to get killed. It is also possible to
buy nylon locking fuel line clamps that you squeeze into place around
the tubing, and the little teeth of the clamp slip over each other and
lock together - these are susceptible to getting brittle and breaking -
with no advance warning. Avoid them like the plague.

I found some small "t-bolt clamps" that won't pinch the fuel line
like these: but smaller.

I'll have to look at the hanger and see if I can find the box.
