Default Aftermarket fuel rail fitment on sqauretop manifold.

Thinking about going to a FM or Radium fuel rail on my BP4W swapped NA while adding flex fuel and converting everything to AN. Just not sure how they will fit under the square top plenum with a fpr and damper. I've really only been able to find examples with the skunk manifold. If anyone has a setup like this some photos would be greatly appreciated.

Lookup any european shop selling VVT conversion kits.
Bofi Racing, SPS Motorsport, Hummelink?, ...
Most of them use the radium rail and aftermarket FPR

Our budget solution is simply using the EUDM NB 99-00 return style fuel rail, Plug and play.
