Pretty simple procedure. Disconect the fuel lines useing line wrench.You should unplug the fuel pump for safety.Unplug injecter harness at the back of the intake.Remove the 4 bolts holding the fuel rail down.Lube the lower O rings with a little wd40. Pull one side up at a time.Make sure the old o rings came out of the port.Unplug the wires and pull the injecters out of the rail.The wires should be tied so you can't put them back on the wrong injecter.Use new Orings with a little lithium grease on them.Makes them easy to install.Reinstall.Sometimes the fuel regulator can be hard to get the return line threaded into.I've found it's easier if you remove the regulator from the rail,get the return line threads started and then reinstall the regulator before tightening the return line.Make sure the Orings are still on the fuel lines when you reinstall them.
