#T-92-116: LOSS OF POWER, HESITATION ON TURNS(REPL. FUEL PUMP STRAINER) - (Jun 29, 1992)
SUBJECT: MOMENTARY LOSS OF POWER OR HESITATION ON TURNS
MODELS AFFECTED: 1990-1992 DE VILLES, FLEETWOODS, AND SIXTY SPECIALS
Some 1990-1992 DeVilles, Fleetwoods, and Sixty Specials may experience a momentary loss of power or hesitation while driving on sweeping right-hand curves, such as an exit ramp, or on hard right turns with low fuel level (generally six gallons or less).
Vehicles that have the above symptoms may have fuel pumps and strainer assemblies slightly mispositioned on the tank sending unit causing the strainer to not stay fully submerged in fuel.
To repair this condition replace the fuel pump strainer with P/N 25121783. This new strainer will stay submerged in fuel to prevent starvation.
Parts are currently available from GMSPO.
Also check for a loose anti-slosh baffle
