Fuel Rail Help
 

Going to install a ported lower plenum. Have the four bolts off and I still cannot get this rail off. Any tips?

If you look at the Engine Mechanical section of the service manual page EM-42, you can see a flange joint in the fuel rail at the front that needs to come undone to separate the rails from the feed pipe as well as the 4 bolts on the rails. Once this is off, you can gently wiggle the rail and the injectors should come out from the manifold.
