Here's something interesting for you Joe. I read on the Docklands liquid LPG site (the mob in the long-running Ford patents dispute) that they started off in Adelaide. That rang a bell with me, so I looked up an old magazine called High Tech Performance or something. It had articles about fitting ABS and some articles about fuel injection, and one about LPG injection
Sure enough, the LPG company was called Liquidphase, the name referred to on the Docklands site. They had a conversion for Falcons undergoing testing, and were aiming for production within 12 months at a cost of $2500. The magazine took the car for a drive, and reported that it had more power on LPG than on petrol, but it ran badly when you were switching fuels. The date on magazine? 1996! That's right, 12 years later and they're still not in production
By they way, they used the original petrol injectors, modified to take liquid gas as well (which they still do, according to info on the Docklands site) so I wonder if they've had any explode. They also used a Magna EFI fuel pump in an APA tank, which sounds like a low-tech backyard job. I've read that petrol injectors would thoeretically work in a liquid gas system, but petrol injectors can't handle more than 120psi, so would explode due to the higher pressures in a liquid gas system. Eg Siemens DEKA II LPG injectors can handle 400psi
