cost factor!

think about it.... both my cars are delco efi & lpg......with vapour lpg
i dont need a fuel pump in the lpg cylinder and im not running high line
pressures in the engine bay.  so apart from that i love the thought of
liquid injection but the tanks with pumps in em are very$$$$$$...that is
unless you guys in the states run a different system ....say  take the
lpg into the engine bay at tank pressure then regulate it to a lower
pressure which even when the tank is low it will still give good
pressure then inject it .......all i seem to have happen is injectors
freezing .......ummm i spose you get that with lpg eh!???

any thoughts??
