Solenoid valve (does this exist)?

[Deni]

I've installed a lpg system on my car and I'm in the process of tunning it. One valve though would help a great deal.

I need a valve, to control the lpg flow, that is activated from pressure (from the boost of the turbo). As boost increases so does the flow of lpg. Does such valve exist? If yes, do you know where I can find one?

Thanks a lot!
