RavTufts, go under the rear seat, unplug the wiring to the sender/fuel pump, start the engine, let it run out of gas.
Crack the banjo bolt on the fuel filter only if you want to change the fuel filter or if you cannot move the fuel line from the fuel rail, (the fuel filter is almost under the air filter, drivers side, bolted to the inside of the front wing, about 5 inches in diameter), otherwise leave it alone, the presure will have dropped and you can remove the injectors. When I did mine I just left it overnight and the pressure had dropped.
You'll need to crack off the banjo bolt on the end of the fuel rail and keep it held up high to stop the fuel bleeding out. You'll also need new O rings/washers when you refit the banjo bolt, as you will on the fuel filter banjo if you remove that too.
There are rubber O rings on the injectors, from memory there are a couple each on the injectors and one thicker one that goes between the injector and the head, they should all be replaced, certainly if you remove any then replace them with new ones. The thicker ones may be on there last legs anyway.... Rockauto has plenty. Good luck!
