operating a 912ul on ethanol

My recommendation is that it is not worth the savings. I have the newer fiberglass tanks and I am getting to flush my fuel system. Man what a PAIN!

Flush them in accordance with Service Bulletin #60 and you should be good.

I just drained 26 or so gallons of fuel, found a place to recycle it and the Plan is to starting the Process of flushing Saturday. I hope all goes well!

paul , maybe youve seen this picture already but this is what i got out of the tank doing the three rinses . the tank wasnt installed yet so it wasnt too bad . if i had to do it on the airplane , id probably remove the finger filter and install a barbed fitting with a hose . this crap would never get past the filter . i havent had a chance to play with the acetone i did the rinse with yet but it smells like resin . good luck .

I hate to be dumb but what is a finger filter? The fuel filter?
I purchase a sump fuel tank drain fiting from Aircraft spruce, I plan on installing it on the header tank. It will allow me to use a hose, and lock the sump drain open so I can drain the tank without worring about getting the acetone on the paint.

Ahhhh Finger strainers, aka tank filters! Good Idea, when I replace the hose for the sight gage, I will pull them!

[cap01]

yes , the tank filter/strainer . course screen , keeps the big chunks from leaving the tank and going down the fuel hose .

Well, I have replaced the Header tank, I have gotten a new fuel filter in from Summit Racing, 703KA had a Earls' 25 micron filter so am replacing it with the same. I had a little bit of a Fuel leak.

Picture #1 - Oops a little Fuel Leaking, my better half was complaining about the smell of fuel! I wonder why??
Picture #2 - The two fitting that were causing the leak, as installed.
Picture #3 - I Replaced fitting and got rid of one pipe thread reducer (the Blue pipe thread fitting)
Picture #4 - Added a back flow valve, per John McBean, to prevent fuel from flowing back up to engine in case of Fire!
Picture #5 - Earl's Fuel Filter, I took the old one out, after cleaning and reinstalling it, because it did not have a Flow direction indicator on it, so I ordered a new one! I will replace it next!

Next up is to put some fuel in the header tank to assure it doesn't leak!

Hopefully over the Christmas Holidays, I can finish the tanks and fuel lines up so I can flush the tanks. All, just in time to get it's annual done. I need to talk to Steve Quiones my A&P about doing the Annual!! I also need to do my BFR Flight Review!

As a quick explanation for clarity, in Paul's pictures 1, 2, and 3 these fittings are on the side of the tank, not the top. The photos are rotated 90°.

[Paul Z]

Si! You are correct the pictures are rotated 90 Deg!

[Paul Z]

Well the header tank is back in and there are NO LEAKS.
Thanks John McBean for all the help!
Now to get the Annual! The Annual is not due until January.
However, I am not putting it all back together and then having to tear it all apart again for the Annual.
