About to start my first annual and want to change the fuel filter from the single unit to two under the seats like others have done.  Are folks just using a second ES Airflow filter or something smaller?  Would appreciate part numbers if you have them.  Jay Rowe #40301

I have done this in one installation and used the ES Airflow filter from Airflow Performance on both sides.  I really like the quality and serviceability of this filter.  Note, however, that to remove and clean the filter, the fuel tank will have to be emptied completely because there will not be a fuel selector valve between the tank and the filter to provide a fuel shutoff.

I put one of these filters in each wing root and theyâ€™ve worked great over 150hrs. Easy to clean and access in the wing rootâ€¦

what flow do you get for takeoff? My EFIS shows a  24 gph rate for full power; I am using the Lyc IO540 D4A5.

Just finished my second condition inspection.  I too, thought about 

changing to move the filters under the seats.  I purchased some of the 

auto racing fuel filters.  I don't have the part numbers here with me at 

the office.  Anyway,  instillation would be straightforward.  I planned 

to put some valves on the tank side to not have the fuel problem with 

changing them.  As I look more closely at them, I decided to leave the 

stock set up alone.  I think David's post is asking the question of 

proper fuel flow with the other filters.  The stock filter in the tunnel 

has a very large screen surface.  The automotive racing ones and the one 

from wicks noted unrestricted flow at 15 gal/hr.  At take off,  I also 

see upwards of 22-24 ga/hr flow.



I also noted the screen size (about size of dime) looked like a great 

place for a contaminant obstruction.  A good size Texas bug could easily 

knock out 50% of the fuel flow.



I also read another post somewhere that high up in the reasons for 

experimental aircraft to fall from the sky was fuel system 

modification.  Decided not to do any more test piloting.



I made up a wrench to fit over the stock filter and it isn't as bad to 

change as it could be.



Tim ; good post on the wheel pant bushings.  Starting to see the same 

changes.   I had to re torque mine this year.  Will make some spacers 

the next time I have to get down there.

I made this cutout under the fuse to allow access to my filter from underneath. Works good.

The filter is good for 15gpm, 

which is 900gph - way more than

 what an IO540 consumes.....

The Wicks filter I quoted earlier has a large filter element - much larger than a dime, more like 1.5 - 2 inches. When I was building, I was concerned about having only one filter - if it gets blocked you're coming down. With a filter on each tank, if one gets blocked, switch to the other tank. 

Also, I don't like the hard to access filter in the tunnel. Filters in the wing root are easy to access. The Wick's filter quoted before will flow 15gpm, which is 900gph - way more than required.

I am not sure this is true for the stock build.  I would have to go back and

look, but there is a bypass line and check valve built in.  I am not 100

percent sure, but maybe 90 percent.



Anybody else know for sure.

I guess I don't see the issue here.



After building plus 4 condition inspections, I find the stock filter  

removal and inspection a very simple matter.



You have to open up the tunnel anyway......

There is a bypass around the pump if it stops or to relieve excess flow, which goes back to the fuel selector, but no bypass around the filter.

This is correct.  If your filter becomes clogged, you will have no fuel flow to your engine.  I have never seen more than just a little bit of "lint" in the filter when removing for cleaning.  Usually any sizeable particles would be caught by the finger strainer in the tank or be sumped out.  It is a good idea to periodically remove the sump drains and drain at least a little bit of fuel from the tank, which will help remove any particles that settle to the bottom of the tank and possibly other particles that are too big to get through the finger strainer in the tank.  I personally think you would have to try extremely hard to intentionally cause a problem to be able to get the Airflow Performance filter clogged to the point of preventing enough fuel from getting to the engine.  I think you would much sooner clog your finger strainer in the tank, of which you have two.  The purpose of putting in two filters, IMHO, is to allow for easier removal for inspection by placing them under the front seats.
