"I've heard of disconnecting the fuse that runs the fuel pump, then starting the car, and that way you don't have fuel pressure issues when you open the line. Just a thought."

Please don't pass that myth around. It doesn't work. Think about it: How will you start the car with no fuel pump?

There's no fuse you can pull without stopping the engine and leaving residual pressure in the lines. Just loosen a fitting and wrap with a rag to catch the small amount of fuel expelled.
