Hi. I have a question about the fuel filter, Im going to pickup a set of fuel filter removal tools. Little plastic clips to remove them? Whats up with that? Anyway, Is there a great chance of breaking the lines doing this? Assuming there not terribly rusted?

I'd soak em good with PB Blaster or such, if one side has the clip the other side maybe a flare fitting, that's where the trouble can start, soak that up good also and use line wrenches.
