Header tank low fuel sender?

[kmach]

I was looking at those sensors on the A/C Spruce site, It's good to know they will work ! I will have to try one.

I am not sure that the header tank on the Series 7 (my plane) is any different than the header tank on a Series 5. I would guess they are the same but I would want to verify that.

This fuel sender had pipe threads and it installs in the bushing that goes into the top threaded hole that is located on the pilot side of the header tank.

I have attached a picture of my tank with the sender unit installed. I am guessing it is probably 1/2 inch threads but I would have to take my seats out to look closely at it and I am not planning to do that until my next annual. Aircraft Spruce can probably tell you as they have been pretty helpful with technical details whenever I called them.

I installed a little red light in the panel that will illuminate (meaning low fuel in the header tank) and I also installed a push to test light that is part of my preflight check.

In my series 5 there is an aluminum header tank, it has a hole on the upper pilot side that is filled with a blue plug currently. this is an old picture before I remounted the header tank, and rerouted fuel lines, relocated the fuel filters and added fuel shut off' s for the wing tanks. you can see the old not working low fuel sensor that is mounted on the vent line, I'm not sure if on the vent line is where it is supposed to be, but it didn't work so it was removed anyhow.

Dorsal/War Eagle: the plastic molded tank is ethanol safe isn't it? they don't slosh those tanks with sealer do they?

I'm going to get the plastic float - price is right, and the optical plastic ones even the mfg emailed me and said they don't recommend the plastic for gas only the metal optical sensor. ($195). Too rich for me if that float will slide in the 1/2" thread hole

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.

Looks similar to the factory supplied one Rob.

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

Here's some pics of it installed.
