Fuel Tanks

The Low fuel sensor is from ACS. It has a magnetic switch in the body and a
magnet in the float. In this shoot the sensor is up side down. As the fuel level
is over the sensor the float is in this position away from the body of the sensor. When the fuel gets low the float drops with the magnet causing the switch to activate. This signal could then run a
pump with a timer or just light a low fuel warning lamp. Then you can manually turn on the transfer pump or look for the nearest filling station!

I tried to make the fuel lines from the stub wing tanks be as compact as possible. I made the hardline connections up on the work bench. Guess what? It did not fit the area. Time to remake all those hard lines again. It looks complicated but it really isn't. The fuel comes out of the two wing tanks via a 1/2" aluminum line to a distribution manifold. From the manifold there are two lines going out to separate filters. From the filters they go to the Facet fuel pumps and on through one way check valves.

The lines meet back into a "T" fitting and on up to the header tank. The second transfer pump is a redundant backup because I will have some long flights over water, if I can't get the fuel to the header tank, then I can not get it to the engine.

The dash 3, Teflon lined, SS brake hoses can be seen coming from the landing gear in this photo too.
