the leads (~0 resistance), it reads just under 3/4 tank.  So either
something's too resistive or something's not getting enough power. 
Where do I start?

Sounds like the voltage stabilizer is set too low.  Try replacing that
thing with a known good one and repete the tests.  The short test should
send the needle well into the full scale reading.
