Fuel - Momentary Loss of Power Hesitation On Turns
Bulletin Number: 92-6-55Reference Number: 206502R
Publish Date: 7/92
Subject:
MOMENTARY LOSS OF POWER OR HESITATION ON TURNS (REPLACE FUEL PUMP STRAINER)
Models Affected:
1987-1992 BONNEVILLE MODELS
CONDITION:
Some 1987-92 Bonneville models 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, when fuel level is below a 1/4 full designation on the fuel gage.
CAUSE:
Vehicles that have the above symptoms may have fuel pumps and strainer assemblies slightly mis-positioned on the tank sending unit, allowing the strainer to not stay fully submerged in fuel.
CORRECTION:
Replace the fuel pump strainer with Part Number 25121783. This new strainer replaces the old strainer on all Nippondenso 51 mm fuel pumps and will stay submerged in fuel to prevent starvation. The Nippondenso fuel pump can be identified by the number 16, (or 51 for supercharged engines) on the I.D. Tag which is attached to the wiring harness.
