GENERAL MOTORS recall on C SERIESK SERIES, and SUBURBAN models

On certain vehicles, the service-part fuel tanks may have one or more pairs of the six projection welds which attach the sender-unit ring to the tank that do not meet specification. These out of specification welds may fracture during sender unit installation resulting in fuel leakage and a possible vehicle fire. Note: recall covers 1975-1986 chevrolet/gmc c/k pickup and chassis cab trucks and 1987-1991 chevrolet/gmc r/v pickup and chassis cab trucks. Correction: vehicles with fractured sender ring weld pairs will have a new fuel tank installed.
