Hi dose anyone no of LPG Auto Converters that can fix a Technocarb EFS600. it turns of from petrol and will not run on lpg. It is fitted on a Ford Triton V10 6.8l. I have found that if I pull the fuse on the battery it will not start on petrol, there is power to the unit as the switch lights up and the relays click over to stop petrol, and open the LPG solenoids but nothing. Have LPG from the tanks up to the venture mixer.
