Anyone ever removed and replaced the fuel pressure regulator on a D1 without removing the Plenum and all the associated crap with it?

 

I changed out the regulator. I did remove the Plenum, but I still had to move the coil pack back to reach the bottom bolt on the regulator. I think that you could actually not remove the Plenum but remove the coil pack completely (undo the wires, unbolt the 4 nuts holding it on, and pull it completely out) and reach the regulator and remove/replace it that way.
