the pump itself where its mounted in the tank can be dismantled, but to do this you need to drop the tank to do a proper job, and simply a rinse filter in petrol etc and will clean it, most though take this chance to uprate the pump from places like matt lewis.demon tweeks/burton etc at same time, as when they do get clogged it puts them under huge strain so they will no longer be as good, but thats worst case scenario as a new fuel filter may do the trick as that traps far smaller particles
