where can i find or buy a lpg regulator that is adjustable by boost pressure? The higher the boost the more gas it lets in.

well not a regulator as such but a b2 or l converter will do this via the balance port on the front cover

It is just a vacumn line that runs between the lpg mixer and converter that is regulated by the vacumn created by the engine, this is how most lpg system work anyway but you will need greater sensitivity to vacumn.

If I've got got it right the vacumn sucks on this set up so how will boost pressure work on it< or could you use the vacumn on the diesel engine?

on a standard n/a engine is sees vaccume
if you are runnign a turbo setup it sees boost and feeds more gas vapor to the mixer
you need one with the metal cover as the plastic ones flex under boost
if i had a digicam id takea pic of my b2 converter and show you what the go is but digicam is on holidays

How is it being setup ? the lpg mixer should be upstream of the turbo/ blower so vacumn pulls it in. On an impco converter, you remove the brass mesh screen and screw in a small elbow for the balance line. More info on the intake setup will help.

so this br uses suck or blow and can the gas flow be adjusted from 0-to-< gas flow.
I am trying to work out a system that i can use on a diesel engine that uses the boost pressure to open the regulator/converter at a nice steady flow. the regulator/converter needs to be adjustable to work from 5psi boost to 12psi boost. do you know if the boost pressure stays up at highway speed say 100kmh or does it drop?

the best way would be to use either liquid or gas injectors. simply use hig pressure reg then an ECU to regulate the gas with the injector.
personally i would be pooring in he as when the motor is at off boost, so it helps the turbo spin up faster and its less likly to blow a motor.
