Hi I need some bits for a 4.6 thor lpg kit I need the lpg injectors and or the inlet manifold already lpg converted

I have the rest or the kit it's s tartarini I know very little about lpg systems but I hope it's just a case of get the injector bars pipe it up and I am off

The reason I ask is th previous owner had a new engine fitted and the garage threw everything that was strapped to the old engine away !

I have checked the engine harness and it seams to be still integrated with the lpg etc so hopefully I just need to get some injectors and pipe it all up again
