Your fuel filter is on the left hand side, the fuel filter comes together as one assembly with the priming pump, two 12mm socket nuts and the whole unit comes off. You can then take the water trap off from your fuel filter, unscrew the fuel filter, change it and put everything back together. It shouldn't take more than 15-20mins max. Fuel filter and the water trap might be a bit tighter than normal so if you have a vice it will make it a lot easier. Be careful not to damage the plastic water trap on the bottom of the fuel filter
