Im considering getting a 123 series 280 to convert to lpg, has anyone done this, is it possible? any help appreciated, thanks

 

A friend of my son is converting a 300D to burn veggie oil, used veggie oil. My understanding is the engine is pretty well set as is except for injectors and some other modifications, It's the fuel delivery where he is running into problems, and of course, cleaning the used veggie oil, which he can get for free or almost free from restaurants. I'll check with my son and see if the person has the car running yet.
