How close to the exhaust is the supply line as the lpg supply line should be cold until it gets into the regulator not warm.Is the supply line heat shielded as it enters the engine bay or getting a full dose of exhaust heat?Is it the vapor injection gas system or the old style.What regulator and system are you using?OMVL ?sprint gas or other cheaper variants?It really sounds like a fuel delivery issue as you are not getting the volume of gas required at higher speeds.Commodore engines have issues with thier water system having air bubbles that cause air locks in the regulators by the time youve jumped out of the car to check for freezing it appears to be fine.You may have restrictions in the lpgas filters/locks.The water hoses,2,should be hot so hot you cannot leave your hand on them and if not freezing of the reg once again becomes the issue.Also the water hoses must be fitted in such a way that the top hose is suction and the bottom hose forces water into the reg,this is done to assist in eliminating potential air lock problems.To sum up your symptoms are consistant with poor water ciculation.

Over heating problem and problems associated with duel fuel


If the overheating occurs when on gas (LPG) I would be looking at a problem converter /regulator for the gas as it may be too lean under load . If you have a viscous fan hub then that will also cause over heating as the engine is working hard but there is little air flow through the radiator because the fan is not drawing sufficient air to cool it.. As the octane rating for petrol and LPG is much then same then Make sure that the ignition timing is correct. Find a service shop that specialises in LPG fuel cars and they may have a dyno that they use to get optimum performance out of both fuels .

V6 holden engine on lpg just stops while driving !


If the filter has already been changed, then the pressure regulator, which also acts as the vaporiser, must be suspect. It is equipped with a soleniod valve that shuts of the flow when the engine is not running,or if it thinks its not running.
