Hi all, I have a 94gt converted to run on LPG because the price of gasoline in england sucks.
Will I need a new computer to accept the new fuel or can I just get it chipped?  

I am assuming LPG is Liquid Propane Gas? I am not sure what you need to converter for that stuff! MM&FF featured a car many, many years ago that ran on propane. I remember it having high pressure rails and injectors and a special pump. For the life of me, I cannot recall if the guy was running stock electronics or some sort of stand alone fuel injection.

Probably about the best thing I can suggest is search the net for information on LPG vehicles from the Big 3. I know Ford has produced several of those vehicles for government use, which include Econoline vans and Ranger trucks. I also want to say that the 160-pound injectors that people buy from Ford and Dodge dealers for thier racecars were used for the propane-powered vehicles. I could be wrong on that though. Roush has done extensive research in the matter and they are also going to release a propane-powered F-150.

Good luck with the project!
