should be able to relieve line pressure by using the release located on the fuel rail on the intake manifold if it is in any way like most typical 4cyl's with injection. Look for something on the rail that looks like a valve stem.... worst comes to worst let it sit overnight and slowly release the nut/bolt/bolts holding the fuel line on at the input side... although it might spray it will do so somewhat controlled and it will relieve the pressure out of the line. Good luck! dude_33694@Yahoo.com
