Compressed natural gas conversions can be readily done, many taxis in KL and Hong Kong are converted, I think some in Singapore as well. Big tank in trunk, no place to put luggage. Mainly consists of carburetor change out and ignition timing.
On a car with a carburetor its pretty easy. Attach adapter ring / mixer to the air intake, gas hose attaches to a nozzle on the ring, attach air intake hose to the adapter ring. A few years back, when it was legal to do it in the UK, I fitted this simple system to a Rover 827i. No need to change the carb. Not the most efficient implementation but it worked fine. I also went for the option of the doughnut tank in the spare wheel well which at least provided the option of retaining all the trunk space and lucky I never had a puncture when the spare was not on board!
I later had a system professionally fitted to a Jeep Grand Cherokee with fuel injection and that does mean replacing the injectors and is much more expensive.
