Buly,
 
Try this one. I have purchased it for the high pressure side.

 
Cost-effective filtering for your engine.
These Aeromotive fuel filters feature an advanced flow-through design, to allow steady fuel flow with less than a .15 psi pressure drop. Designed for carbureted or fuel-injected engines from 200 to 1,000 hp, they're made from 6061-T651 aluminum alloy and have a 10-micron filtering element for reliable protection.  Not sure about the cost effective part.  I am also planning to use the same filters as Ed A and Egg subi package. . on the low pressure side. I will check pressure loss during testing and make a final decision based on head pressure, wing dihedral and pressure loss etc. Those filter bags that Al is mentioned look good as well but I am not sure I could retrofit them into my RV10 tanks. I figure within the next year their should be another 100 or so Egg's in the air so that is a pretty good test group.  Bobby

Hi Ed,
The cars take fuel an inch or so up from the bottom and avoid most of the sediment. I have cut gas open tanks and  you'll be surprised what's left inside after few years. At least on my plane the fuel is drained at the tank's lowest point, and I would like to have any sediment or water to come out and be trapped in the filter/water separator, instead of accumulating on the screen inside the tank.
I'm nervous about installing high pressure filters in the gas lines, but that's my opinion. Just another 2 connectors that can fail? One day If I'm proven wrong, maybe I'll install one too :)
