This is what happened when my brother and I changed a rusty fuel filter.

i've changed two this way.

Release fuel pressure... get car in air.

Undo the quick release and put a line wrench on the fuel line nut. Then using another wrench turn the fuel filter...holding the line wrench steady. Do not let the line wrench turn and damage the fuel line.

I think it'* a 15mm on the line. It took a little PB blaster and wiggling to get the wrench on. Then the filter is large... I forget what size.
