I'm pretty much sick of emissions, and trying to find almost any legal way possible to weasel my way out of it. So I'm exploring the idea of converting my FJ40 to propane.
I've heard that fuel mixers/converters will freeze up in the cold. I've never had a problem with this, and have used propane appliances well into the -30's. However I'm aware that this is probably an anomaly, and I need everything working at -60 and below. What parts need to stay warm? I assume that as long as there's pressure in the tank, that's not an issue, but the converter and mixer seem to need heat. I've seen that the kits use a coolant line to heat up the converter, but what about heating it while the engine's off? I was thinking about maybe using one of those inline coolant heaters to keep it warm until the engine warmed up. The mixer I would think would warm up quick enough not to be a problem.
I'd also need a tank. I've read that the old Baja racer FJ40 had a 20 gallon propane tank mounted under the bed somewhere. I could probably do the same. The problem is our beloved Alaskan roads are long enough that I'd need to find a way to bring propane in tanks and either switch them out or find a way to refill the big one. If I got some forklift tanks I could easily swap them out, but that would cut the capacity in half (they're only up to 10 gallons, right?). Any ideas?
