If you don't have a AFPR you undo the two fuel hoses at the green arrows. If you do, you undo at the red arrows and you WILL have to slit the hoses to get them off the barbs. Make sure you take off your gas cap before undoing the hoses and have a rag ready to catch a bit of gas. Yeah GASOLINE, as in EXPLOSIVE vapors! You don't have a forced air heater next to the car do you? A water heater? A cigarette? Please, if you want to blow yourself up, spare your Miata!
