I need schematic because I do not know position of that fuse, I guess left from brake. I have I30 97.. I want relive pressure in fuel system to change fuel filter.

 

fuel isnt going to burst out. just slowly pop the line off and some fuel will dribble out, quarter litre if that. if youre really worried wear safety glasses and rubber gloves but ive changed hundreds of fuel filters and never pulled the fuse

 

it is on the left driver side near leg..inside the fuse box cover it is listed in the diagram on the inside of the cover ..at least on my 98 gle it is..forget what number it is off hand

 

^This. It's listed on the panel. It's in the far right column, 6 from the bottom.

 

Thanks guys. That photo will help. I do not have it at my fuse box cover. Probably fell off. Will copy that picture to have for future.
I did job. It was somewhat tricky. After detach upper hose you have to pull out filter from sit and get below another hose and up so you can twist filter and expose lover hose screw. After that is easy. Guess would work without pressure reliving as Chrome said.
