(GeoR38@aol.com) ________________________________ Message 1 _____________________________________ Time: 05:08:30 AM PST US From: Ron Hoyt Subject: Kolb-List: fuel line bubbles-Follow up --> Kolb-List message posted by: Ron Hoyt 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.

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.

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.

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.

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?

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.

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.

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.

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.?

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.

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. john h MKIII/912ULS (with hose clamps) ;-) --------------------------------- Bring photos to life!

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. Jack B.

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.

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.

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 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. http://store.qualitydist.net/tboltclamps.html I'll have to look at the hanger and see if I can find the box. ________________________________ Message 39 ____________________________________ Time: 11:27:34 PM PST US From: GeoR38@aol.com Subject: Re: Kolb-List: Different occupations of Kolbers? --> Kolb-List message posted by: GeoR38@aol.com In a message dated 1/29/2006 5:50:17 P.M.
