I would have it checked for a leak, when LPG leaks it will cause freezing of the valve. LPG under pressure gets extremely cold when it is released. I see this all the time around shut off valves on propane tanks. I am not a Toyota Mechanic so I can't say for sure, but it sounds like the regualtor has a small leak in it. Some fork trucks use these regulators and I have seen them freeze up just from being used as gas passes thru the regulator. does this freeze up when you are using LPG or does it freeze up all the time. If it is freezing while not being used, I would definatly have it checked for a leak.

Why does the system fuel light keep showing on my landcruiser workmate 70 series 2004 yr

did they replace the fuel pressure sensor. as this could be the problem. it could be over pressure or underpressure, that could be the regulator is blocked or the injector filter is clogged. but if no change in any driving needs then would just think it was the sensor as the others would limit fuel.

Lpg system has no gas getting to inlet manifold

you might want to check out the lpg regulator , it may have a blockage or some other problem with it. If it's a dual fuel system you mau want to also check the electonic switch that switched it from petrol to lpg. Another thing to check could be the lpg lines and joiners, a leak in these may cause the system to shut down. On top of all of that you may need to check that there is no blockage in the lpg line or the jet where it goes into the manifold. hope this helps.

LPG probs

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.
