    Yes as far as I know they are ethanol safe. Also if I recall correctly the float type sensor threads directly into the plastic tank with a good and liberal amount of sealer (my first try did not seal completely). My setup looks the same as WarE's including the return line.

    The header tank is defintely different material than my wing tanks. I am guessing it is a poly type material rather than fiberglass like the wing tanks.

    Never heard of the header tank being sloshed or coated.

    The low fuel sender I got from aircraft spruce isn't going to work in my model5's aluminum tank. The sender is too big to fit in the side top fitting, it was worth a try though.

    Kitfox do a kit which has an additional tank which sits above the header tank and has an opening for the larger sender. I have the kit but have not yet fitted it

    Hey I have the optical sensor, and the foel low light comes on even if the header tank is full. It seems sunlight does ahve an effect, when flying below a thik cloud the light goes out, when the sun comes out the light comes on again. Anybody any ideas ??

    Common problem with the optical sensors. You could paint your header tank so no light gets through. Not sure what paint will stick to it. Another common problem with the optical sensors is "melting" (cold flowing) from auto gas usage. Not really sure if it's the alcohol or the other "toxic" additives they put in auto fuel now that melts the plastic in the sensors. Probably why most have gone away from that type already.
