This factory service and repair manual for the 1991 Ford F-700 LPO deals with three engines in a single straight truck body and a single Base trim. Two are gasoline V8s, the 6.1L and the 7.0L OHV, the larger of which was also built to run on propane; the third is a turbocharged 6.6L inline-six diesel of 401 cubic inches. The book keeps each fuel system separate in its procedures, specifications, torque values, wiring diagrams and diagnostics, which is the part that matters most on a propane chassis.

Known issues on the 1991 F-700 LPO. Federal records hold nothing against the 1991 F-700 LPO, neither a recall nor an owner complaint. The coverage stands on its own merits: procedures, specifications, torque values, wiring diagrams and diagnostics for the 7.0L OHV V8 on propane or gasoline, for the 6.1L gasoline V8 and for the turbocharged 6.6L inline-six diesel, along with the straight truck chassis they were fitted to.
