The first 331's produced were basically a 331 ap/gpu. The fuel control
and pump were driven by the torsion shaft. Not a very good idea for
something turning a prop. Afer a handful of fuel system failures like the
one described, the diaphram was redesigned to use the main shaft
instead.
The 840's were manufactured after the problem was found and are already
the new design. I think most of the -251, 252's came out with the newer
design also.
I would be very aware of this issue if I were to purchase a pre-century
or century series 1 or 2.

>>>For anyone concidering a Garrett 331, if it is a model that developes less 
than 840hp, make sure that the Direct Drive Fuel Control mod has been 
accomplished.
