Does anyone have any advice for changing the fuel filter?

I bought a new one and I am looking for advice here before I get started. Is the system pressurized? Where is the filter located? Is there anything I should be aware of that may affect performance?

Any comments are extremly apreciated....

Thanks;

Adam
