I am in the process of converting my P38 to LPG and have a question regarding the tank solenoid. I have seen / read about some systems where the solenoid is simply energised when the ignition is switched on. Would it not be better / safer to supply it from the fuel pump circuit so that it is only open when cranking or engine running? (Obviously it will also be open for a few seconds at ignition switch on, as the pump runs to prime the petrol fuel rail).
Cheers, Chris.
