Which fuse should I pull before replacing the fuel filter starting to disable the fuel relay? I am conflicted here. My manual says 11and 12 are the injectors and pump but I have also seen people who say 8 which is listed as control modules/engine auto transmission. 8 is the larger 60A and 11 and 12 are 10A and 20A. Sorry, I am sure you know all of that. I am just explaining what I see and heard.

Hello again.

Here is the information you requested. In the under hood fuse-relay box is where you will find the relays for the fuel injection system and fuel pump relay. The fuel injection relay is in #1 location and the fuel pump relay is in location #103. I've attached picture below showing the locations and marked in red. Here is a tutorial showing how to test relays:

Hope this helps and thanks again for using 2CarPros.
