Gascolator and filter

[kitfox2009]

Hi Dave
I have no filters in my system. Only the fine screen in the gascolator. In 200 hours I have had no issues. Actually, the inspector would not approve an "in line" filter anywhere in the system. Apparently problems have occurred with moisture swelling the membranes and restricting flow. I buy my fuel at a bulk dealer and store in a 45 gallon drum. I have a very fine filter cartridge and water separator on my hand pump. I also hanger the a/c.
Cheers

FYI: If you have one of the Ellison Throttle Body Injector carbs, they have super small holes for the fuel (in order to atomize the fuel) and require a fuel filter with 70 micron or finer filtration (I use a large paper auto filter myself, if it expands, it still has good fuel flow in my experience.).
Hope this helps
Roger

I noticed Aeromotive makes a sweet replaceable FABRIC element fuel filter, with 10 microns of filtraton, but it's not cheap:

I also notice it states not for use with E85 or alcohol.

Wow, John, I don't know where you buy or store your gas, but none of these have ever happened to me and I am as old as dirt. I would be willing to wager that 80 to 90 percent of flying Kitfoxes have inline filters. Then keep in mind that the certified aircraft you refer to have either aluminum tanks or rubber bladders. I know of at least one reported instance when glass fibers from the wing tanks clogged a gascollator screen. And it was a s tricky diagnosis as, as you suggest, the fibers dropped from the screen, but were too long to exit the quick drain and were invisible on the bottom of the bowl. Then reassemble and over and over again.
For the sake of argument, I put 900 you're on a Model IV with the purelator glass filters and have them on my current project. Good thing they call these puppies experimental, I guess.

With no gascolator and just small inline filters wouldn't this have stopped things up just as well?

OH man. Throw that gascalator as far as you can. PUt an automotive inline plastic filter, 1/4 inch ends just after the on/off valve. replace the filter once a year at your anual and forget it. I don't have one of those things on my rv either. I've read more problems with leaks and such with a gascalator that I will not use em. Going flyin', yup with an auto filter.

Hi
I would not touch a small inline automotive filter, buy a good quality gasolator such as the andair ones expensive but good quality and large filter area.my certified a/c has course finger strainers in the tanks, a large gasolator and a filter in the mech pump(0-200) and in 30 years of flying I have not had any fuel problems and this will be the system I am fitting in my mk7!!!

Total Mis-information
