Would it not install the same way as the stainless steel pipe? You install it from the back of the jet, with the rear center piece off it all slid in very easily, I would think a fiberglass bifurcated pipe for an EDF should be able to be squeezed much further than the stainless one to insert it? Just guessing as mine is the turbine version, but that's how the pipe goes in on it, through the back end.
