HI, the oil filter is at the front of the engine, slightly to the right. You may have to remove the black platic engine cover.  It should have a 36mm 'nut' shape on its housing so a suitable sized socket would be needed to remove it.
Fuel filter will be under the bulkhead, roughly in the centre just under the windscreen, again its a large black circular housing  ( about 3.5" in diameter.  On some, there is also a fuel filter in side the rear wheel arch.
