In the side of the pump top there are 2 steel balls, you have to drive them both out to get the AFC lever pin out.
Drive one in, the other pops out, then drive the pin backwards and the other falls out.
Remove the pin and the lever comes out.
On the front of the pump, behind where the throtle shaft and levers would be located, there is a plug with a hexagon hole, remove it.
Behind that plug is the fuel pin, remove it.
The hole the pin was in has a 4.5mm hollow "set screw". This is actually what holds the 'O' ring for the pin.
Use a 4.5mm allen wrench to remove the "set screw", then pick the junk 'O' ring out.
Mark.
