Converted a Rav 4 last year and still see it and the chap that owns it quite often, I used a Emer multipoint system and its going well, I would deffo have a flash lube system fitted aprt from that the only real question is which tank to use, as there is limited space. On the one I did we fitted a full toroidal tank in the bbot and fitted a false floor over it. Later we also fitted a small cylinder tank along side the torodial to give extra range. Never heard of a auto box having problems due to a lpg conversion!! Thats a good one! Probably put out by some one who fitted a duff auto gear box! Blame it on the gas every time!
