Hey TAMMY LYNN2,
In this case I would just release the pressure by slowly disconnecting the lines from the fuel filter.
You will lose some fuel during the process so wear protective eye wear so you don't get fuel in your eyes. Protective clothing also, fuel does not do nice things to your skin.
Have something ready to catch the fuel released from the lines.
The pressure isn't crazy high just be careful and you will be fine.
Regards, Joe
