Here's how Honda service manuals say to relieve the fuel pressure
1) Disconnect the battery negative cable from the battery
negative terminal.
2) Remove the fuel fill cap.
3)Use a box end wrench on the 12 mm banjo bolt at
the fuel filter while holding the fuel filter with another
wrench.
4) Place a rag or shop towel over the 12 mm banjo bolt.
5) Slowly loosen the 12 mm banjo bolt one complete
turn.
The fuel pressure will push the fuel out of the loosend fitting and onto the rag. You must relieve the pressure before the fuel filter can be removed.
Another way to do it safely is to pull the main relay out of the connector and crank the engine over for about 15 seconds. The main relay controls the fuel pump and the ignition so the car won't start and the fuel pump wont' run but cranking it over should open the injectors to vent some of the pressure that is in the system. The main relay is located under the right side of the dash between the side of the glove box and the side of the car. You'll probably still have some residual pressure in the line but the fuel pump won't run with the relay out.

if you know where the filter is then just take out the old one,hang the hose higher than the fuel tank and the most important,don`t turn the key into switch/acc position,take note that even if the fuel pump is not running there will always be something that will come out of the hose.How to change a fuel filter in a 1998 honda civic ex?
