Dear General Motors Dealer:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

REASON FOR THIS RECALL

General Motors has decided that a defect which relates to motor vehicle safety, exists in certain recently manufactured replacement fuel tanks sold through General Motors Service Parts Operations (GMSPO). The tanks involved are 16 and 20 gallon service part fuel tanks used on 1975-86 C/K Pickup and 1987-91 R/V Pickup and Cab-Chassis trucks. These replacement tanks may have one or more pairs of the six projection welds that attach the sender unit retaining ring to the tank which may not meet specification. These welds may fracture during sending unit installation. If the welds fractured and this was not noticed by the installer, the tank could spray some fuel in a collision and/or could leak fuel if the vehicle rolled over. If an ignition source were present, a fire could occur.

Service tanks involved in this recall are GM part numbers:

Part Number Tank Size

14071994 16 gallon
15548967 16 gallon
14071984 20 gallon
14040781 20 gallon
15624668 20 gallon
00471687 20 gallon

These tanks service 1975-86 C/K and 1987-91 R/V Pickup and Cab-Chassis trucks. These tanks were produced by GM between December 1, 1993 through September 12, 1994, and were sold through GMSPO. Included with this letter is a list of involved tanks sold to your dealership.
