502 MPI Fuel Rail Assembly
I have a 2006 502 MPI (OKO21346) and am having a heck of problem getting the fuel rail assembly to clear the four runners on the lower intake once the injectors have been freed from the intake. No matter how you twist and turn it, the bottom of the injectors come in contact with the runners. It appears a few of the injectors have to be removed from the rail to get the entire rail free of the lower intake. Is there a trick to this?

Leave the 4 injectors in the manifold on one side and remove the other 4 with the rail....comes out easily that way.

make sure you replace the o-ring on the injector you pulled out or all if you can. They're not likely to seal again. I always dab a bit of grease on them so they don't roll or bind on the way back in.

or, go to just about any fuel injection service company and they should be able to match. Wouldn't be a bad idea to get new filters for the tops either.
If I may ask, why are you taking the rail off?
