Removing LPG

[AussieGreg]

Hi. I am looking for a V8 Fairlane or an LTD from NL/DL series onwards. Some I have seen have had LPG added (Dual Fuel). I am not interested in having LPG as the car will be a Weekend Cruiser/ Cars & Coffee Car, so Fuel Economy is not an issue for me to worry about and have owned V8s before and to me owning a V8 you cannot be worried about fuel economy. Lol
Can some Members please advise what is involved to remove the LPG Tank and associated fittings etc. along with an idea of the costs and the pitfalls to look out for with taking a Car off LPG. I am based in NSW. Does the Car need to be Inspected after the work is done?
Would appreciate your advice please.
