Do you have the Caterpillar secondary fuel filter with manual primer pump?
If so, unscrew(counter-clockwise)the knurl nut. Pump (in/out). When it goes from easy to move (air) to hard to move (fuel is non-compressible) screw it back in (clockwise). Start engine and drive off.
Let us know if you do not have the manual primer pump.
