Posted for "Cy Galley" <cgalley@qcbc.org>:
Sorry, you don't want to pull fuel from both tanks. Tanks don't feed evenly.
At some point in time you will suck air from the empty tank and this stops
the flow of gas even though you may have another tank fairly full.
Redundant pumps will not help this basic problem. Check any low wing fuel
system and you will NOT find the "Both" position that is familiar to high
wing Cessnas.

I am planning to install a T fitting on the IN side of each of my two
Facet fuel pumps and run a short crossover aluminum line connecting the
these two fittings. The purpose here is to provide a connection between
the two wing tanks so that if one pump fails, the other will continue to
pull fuel from both wings.
