Known issues on the 1992 K2500. Three recalls are on the federal record. Two concern replacement service parts: fuel filters that may not seal at the connection and allow a leak near an ignition source, and oil filters whose poor sealing can drain engine oil, either of which can end in a fire. The third is the automatic transmission, which can force fluid out of its vent tube when it runs unexpectedly hot. NHTSA holds one owner complaint for this year, entered under visibility. The manual's fuel and transmission procedures and its wiring diagrams speak to those areas.
