The 1993 Ford F-350 has 6 recalls, the most serious being a dual fuel tank defect where a failing check valve or fuel pressure regulator can cause fuel to overflow between tanks and spill onto the ground, creating a fire risk near any ignition source.
Vehicles with dual gasoline tanks are the focus of multiple related filings describing the same underlying problem: a worn fuel pressure regulator can damage the check valve inside the fuel pump assembly, allowing fuel to migrate from one tank to the other, overfill it, and leak out. The cruise control system accounts for the remaining two recalls. A speed control deactivation switch can leak internally and then overheat, smoke, or catch fire under the hood. There is also a wiring concern affecting vehicles that received a prior repair: a replacement wiring harness installed in an earlier remedy used incompatible polarity, placing the fuse in the wrong part of the circuit so it may not protect against an electrical short.
