Known issues on the 1993 K2500. Three entries make up the federal recall record here. One describes replacement fuel filters that can fail to seal and leak fuel; a second, replacement oil filters that can seal badly and let the engine lose its oil; a third, transmission fluid pushed out through the vent tube by unanticipated heat. All three end in the same place, a fire hazard. Two owner complaints are logged with NHTSA, one on the service brakes and one on the seats. Brake specifications, transmission procedures and the fuel system diagnostics are the relevant sections.
