I want to change out the fuel filter without getting a shower.

 

I don't know the specific answer to your question, but often there is a legend on the inside of the cover of the fuse/relay box that describes each component inside. Start there.

 

Thanks for the response.
The owners handbook and fuse box provided no information, but Google pointed us in the right direction. We found it on the driver side just in front of the left strut tower - 2 fuses (was the one nearest the engine). We guessed correctly.

We started the car, then removed the relay - the car ran for about 5 seconds after that then stopped.
Fuel filter fitting was a pita to remove - as they all are - eventually got it off and did not get a gasoline shower.
Replaced the relay and after a few extra cranking seconds, all fired up just fine.
