" From: "Brien Tourville" <hh7x@xxxxxxxxxxx> " " " http://www.gas-injection.com.au/index.html jim blair located a company a few years ago, that was developing liquid-lpg injectors. iirc they were working under some kind of grant or funding and targeting the ford 460; they didn't have any smaller injectors that we might use on a 4.0. also iirc their biggest problem was icing on the injectors from the fuel vaporizing. surprisingly i don't recall anything about vapor lock, but if they retained a fuel pump and pressure regulator return line, vapor would be purged almost as easily as with gasoline. ps. got a url for sleeger? do they have anything for the xj? or don't they sell retail? ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
