Barry,
Would you share some details on the mfg. etc. of the clear in-line plastic fuel filters you installed for each tank? I think I would like to do the same on my 6A. Don't know that I need the filtering but like the idea of being able to see the flow. Check my gascolator each year and never find anything in there.

A side note: On the RV6 that I fly I have added two in-line clear plastic fuel filters (one for each tank) inside the cockpit - I can look down and see a positive fuel flow. This works way better than the gascolator.

Dale:
The fuel filters are from an automotive store. Get the ones with a LARGE nipple at both ends. You maybe able to do a little research and find the GPH or GPM flow rate of the filter via part number. Or it maybe written right on the package. The cost of the filters were under $5 each. I had to add a small piece of rubber fuel tube (4 ea) and GOOD hose clamps (Breeze Eastern) (8 ea).
On the RV6 the electric boost pump is located on the pilot sidewall and I just came out of the fuel tank into the filter and then into the boost pump. Might as well filter the fuel to the pump. CLEAN IS CLEAN.
The reason why we did this is we had some crud in the tank and no matter how much cleaning we did there was always something. It showed up first by preventing the boost pump from pumping... NOW! The pump still flowed fuel, but the pumping stopped. The fuel filter shows fuel flow, shows dirt can be back-flushed BUT is so cheap it is better to replace it.
NOTE: Read the install instruction on the filter.... It has a direction of flow stamped on it.

I used these types of filters to flush the fuel tanks and lines on initial build. Cycling a few tank full of fuel through these filters and temporary poly tubing and back to the tank is a good way to get rid of the junk (mostly proseal flakes) before first flight. They also comes in handy for doing the fuel level probe calibration.
I would caution however against using anything in a flying plane fuel system that involves rubber hoses, plastic filters and hose clamps.
Van’s sells a very nice inline fuel filter (the Air Flow Performance unit) that is easy to maintain, meets all engine manufacture requirements, and has proper AN fitting. This filter is also large enough so that if you do have some crud, you will have plenty of filter left between annual cleanings. If you have so much crud that you even see any significant amount at annual, the answer is to fix the fuel tanks as this is not a safe situation. It is recommended the filter be installed between the fuel selector valve and the electric boost pump.
