A fuel system 20 for an engine of a marine vessel comprises a settling tank 110, a service tank 130 and a filtration system 120 comprising a first filter 122 through which fuel flowing from the settling tank 110 to the service tank 130 passes. The filtration system 120 is configured to be operable in a first mode in which the first filter 122 removes contaminants from fuel flowing from the settling tank 110 to the service tank 130, and in a second mode in which fuel flows from the service tank 130 through the first filter 122 to dislodge the contaminants from the first filter 122. A bi-directional pump 124 for both modes, or separate pumps (221, 222a, fig.3) for each mode may be provided. In the second mode, the dislodged contaminants may be allowed to flow back to the settling tank 110 or may be removed by a second filter 125 and collected in a removable collector 126. A controller 140 may begin the second mode at timed intervals or in response to a sensed fuel parameter, eg pressure or mass flow, between filter 122 and service tank 130.
