If you have a Suzuki 4 stroke, there's the paper element filter right in front of the engine in the little bowl, then a low pressure fuel filter, and last a high pressure fuel filter. And you probably have the spin on racor filter before the engine.

You should replace the racor every spring, they recommend the paper element I think every 2 years, the low pressure filter every 500 hours I think and the high pressure filter every 1000 hours.
Order a service manual from Brown's point marine. Worth the money.
