This talk is really about ethanol. I never had any fuel filter problems either... until now.More problems will crop up.

Been flying these contraptions since summer of '78 or '79...hell, I forgot but it's been a long damn time. Everything from a Sachs, to a Yamaha 15hp (what a piece of crap that was), to a Cuyuna (another piece of crap), to the wonderful world of Rotax.
I never gave an ounce of attention to fuel filters & never had any trouble with fuel filters. So what in the heck is all this talk about?

Bill C?
I reckon some of us have not been as fortunate as you have after all these years.
I quit using paper element fuel filters when I started building and flying Kolbs in 1984. Didn't take too long to find out a couple drops of moisture caused the element to expand and shut off the fuel. Most of the time not enough to kill the Cuyuna completely, but enough to prevent maintaining altitude.
I remember flying back to my cow pasture in Titus, Alabama, from a cow pasture between Woodville, Florida, and Natural Bridge. Can't remember that gentleman's name that used to let me land there when I was visiting Brother Jim in Woodville. Anyhow, was following I-10, in my Ultrastar, between Quincy and Marianna, FL. Beautiful day, wind in my face, watching the cars and 18 wheelers passing me, not far below, when the little Cuyuna started losing power. I headed for the nearest tree studded pasture full of horses. Got on the ground, wiggled wires, scratched my head, got the Cuyuna restarted, took off, and headed up the interstate for Alabama. Next day, at Gantt International Airport, I was still scratching my head. I had made 5 takeoffs, followed immediately by 5 forced landings. Took me that long to get around to changing out the little paper filament fuel filter. Problem solved until the next time it got a little moisture in it. Discovered the fuel filter I am using today. No more moisture and fuel filter problems.
I still use paper elements in diesel and gas powered tractors, trucks and lawn mowers. Guess they have updated their paper elements to be moisture tolerable. Still don't want to use one in my mkIII.
What kind of fuel filter is Bill C using? Maybe I ought to get one of those.

So you have also had an engine failure due to a cheap fuel filters, this is a very common story as a previously pointed out. One of your Rotax 912 failures may have also very well been avoided by using the better Aircraft Sprue fuel filter, given the much larger filter area, and the dual filter screens, those fibers that completely clogged your filter may have not completely clogged the Aircraft Spruce filter. As I stated before, a lot of filter area is important, especially in an airplane.
John, you seem to have found a filter that is better than the plastic ones, but not as good as it should be. Here is the problem, the design of the filter you have has changed over the years, that model has been made in China and is now total garbage, I have heard of the threads stripping, leaks, and other problems. Those buying your filter now may be in for a big surprise. Those buying the little plastic filters from the auto store are even at greater risk. For those that want to be Guinea Pigs, keep using those plastic and other inexpensive filters as the Chinese find ways to make them even cheaper every year.
As far as the cost, we all make our choices, I am not some super rich guy that can just go out and throw money around either. I make my choices, and the 80 dollar filter is a priority for me, I did without other things I would have liked in order to buy these filters. As I said before, the 80 dollars is cheaper than any forced landing that results in aircraft damage, and its the bargain of the century when compared to hurting yourself and going to the hospital.
We have seen a lot of aircraft damage and even a couple guys seriously hurt due to poor fuel system design over the years here. There is a good reason as to why the EAA says that about 50 % of engine failures in experimental airplanes are caused by fuel system problems. I have flown with cheap fuel filters and been lucky, but I continually research and learn especially when I read about dangers and problems such as this one. I am honest enough to know when I have made a mistake even if I have been lucky and not paid any consequences. I am also smart enough to learn from and correct mistakes I have made. There are many out there that will take good advice, and there are always a few here on the list like Bill that like to talk big on the list, and cant stand to be told something by a younger guy that has done his research and knows what he is talking about. That is fine, they are free to make their own choices, and will have no one but themselves to blame when the odds catch up to them.

Mike B:
I would think you would have gotten the hint from my post that I am pretty
happy with a fuel filter I have been flying with since 1984, and well over
4,000 hours.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> Dale.. nice post. Being a newbie myself, lurking for years, I have not had the experience of being ridiculed, but instead ignored... wonder which hurts more. I've sent e-mails and questions to several of the gurus, without response.. I guess they don’t read their mail. Jim "invisable" Beard MK lll X under construction, Arizona. (BTW, got my private SEL in '76)

James,
People are usually pretty good about helping new guys here. If you post a question chances are probably pretty good you will get some good answers. Of course, some questions, etc. fall through the cracks, but its not intentional. Welcome to the list, and I hope you come back often. Lots of good information here, and its easier to learn from all of our mistakes rather than make your own 
Mike

Hi Jim B/Gang:
Do you have a copy of the "Guru List"? I haven't seen it and was curious who is on it.
Jim, if you weren't invisible, maybe those Guru's could see you.
PVT SEL 1976. Jim B has me beat by 14 years. I didn't get my PVT ticket until 1990. I was a late bloomer. Didn't need it until I built the MKIII. Started flying at 29 in the Army. That was middle age or better for that environment.
Where are you located in AZ? I am heading West for my annual surface trek in two weeks. Plan to be on the road from two to three months, or until I get tired and ready to head to the house. Last year I split the State from north to south. Might be in your area. I cruised by Dale W's place, missing him by a couple miles, last year, but didn't know it.
Plan on seeing as many of my friends as I can on the trip, from Oregon, south and east. Don't worry, I bring my own bed, bath, kitchen, TV, and dirt toys. Might need to borrow some tools though.
