Ferg,

I'd sure like to see pics of your setup.  



I still have the old, original, parallel pump setup with the glass filters in line between the fuel selector and the pumps.  I'm not crazy about the setup, but haven't been able to come up with what I believe is a suitable alternative.



Right now, I'm thinking about adding a single large Anadir gascolator in-line before the Tee to the glass filters and pumps.  But I need to mount it such that it's easily accessible for maintenance.



Good building and great flying,

 

Bob Borger

Bob,

  

 I have the same ste up and it seems to work very well.  The filters0 are easily accessible and take only minutes to check.  I see no reason0to0 add any complications. The a/c has 140 hours and no problems.

Hello Ferg and all,

 Here comes the thru story of the second filter.0 Mark Waite went with the Europa demonstrator to Friedrichshafen for the Messe0 Aero 2003. There he refulled often from a tank on wheels that was placed near0 the grass runway where the demonstration flights toke place. This tank was0 an old military object that certainly for years wasn't used before it served at0 the Aero. So when I asked Mark to make a night stop at my home field EBLE in0 Belgium when returning to England, he was pleased and we spend a good moment0 togheter. He refulled and started in not very good wheather so that he had to0 fly at 1000 feet agl or even lower. Then his filter became clogged and he had to0 make an emergency landing in Ostend where the filter was found full of brown0 debris. Mark told me that the last refuelling at my place procured him a lot of0 fear.

 Now, I knew better because we never had fuel or0 filter problems in our club. If the tank in Friedrichshafen was as rusty inside0 as outside then the reason for dark brown debris in the filter was easy to0 explain. Next to this came the bulletin for a second filter and a lot of  possible arrangements. For me it is clear. You may add filters and bypasses as0 much as you like, if you don't control what is poured in the funnel than you0 never can be sure. The mini gascolator from Andair is aircraft material and good0 for engines up to 150 hp. When using additionally the fuel filter0 funnel from Smart Tech you may sleep on both ears like they say in0 flemisch....until you tell me another story.

 Karel Vranken, # 447 F-PKRL, final control before0 first flight on september 7th.

Phil Lockwood's Annual seminar on 912/914 maintainence at Oshkosk touched

on the issue of fuel

filters.  He said (paraphrasing):

1) Immediately get rid of paper element filters

2) Gascolators are best option (personally I wait on removing the Europa

filters until all the swarf of spun polypropylene is out)

3) There is nothing wrong with the plastic element in-glass filters

supplied by Europa



He also commented that while the Rotax factory allows 5% alcohol mogas, his

shop has seen

no problems with the 10% alcohol mix in the essentially all (at least

seasonally US mogas.

This does not rule out cheap, ethanol or methanol sensitive fuel hoses.



Much of the rest of the talk was carried over from prior years

Ira,

 	  Quote:

Did he gave the rationale about this advice ?
	


Too low filtering power ?

Too easily clogged ?

After all, millions of four-stroke road vehicles, and thousands of 

airplanes are running with paper filters and without any problem.

Or wasn't he talking about two-stroke engines ? Paper filters are a 

no-no for two-strokes, due to the oil in the fuel blocking the filtering 

element.



But what did he find wrong with paper filters in a four-stroke ?

We're using an Andair gascolator too.
	




Thanks,

 Hello Patrick,

 I think the same maner, I have two europa transparent filters  Purolator, each on the bottom of the two seats, with parallel connection on the  fuel circuit.

 I include the filters control into the pre-flight check.

  

 I don't like the gascolator because it is not possible to check easily  before flight.

  

 I have 300 hours flight now

  

 Europa monowheel N°145 - 912 - Woodcomlp propeller constant speed.

  

 Good flight.

 I have the same ste up and it seems to work very well.  The filters  are easily accessible and take only minutes to check.  I see no reason to  add any complications. The a/c has 140 hours and no problems.
