REFLECTOR: Uneven fuel draw

[Scott Derrick]

First,  we will assume you have the 3-into-1 vent system.  Both main tanks 
and the sump tank vents connect to a block that has one vent line.  This 
insures you have equal pressure in all tanks.

Second,  be sure your fuel caps are sealing. Get some Fuel valve lube for 
this. Its a sticky grease that will not dissolve by contact with 100 
LL.  Be sure to grease the center post that attaches to the cap lever.

Third and the most likely reason is your plane is not trimmed correctly and 
your skidding along in level flight. The fuel will migrate to the outside 
of the skid.   Verify your slip indicator is centered on the then verify it 
is centered in flight. If not, step on the ball and see if after a few 
minutes the fuel equalizes in the tanks.  You can speed this process up by 
stepping so hard on that rudder that your now skidding in the other direction.
