As per phone conversation here are some pics of the injection system fitted to teh same engine as yours but in a 240. All the parts can be mounted in exactly the same positions. Sorry for the delay but I had changed my email address on my profile and this stopped me posting upto now.
Genral engine bay shot
LPG injectors (note they are OMVL but I no longer recomend these)
Position of LPG injector nozzle
