you could have blocked lpg filter
could need to adjust the mixer/converter
may have a faulty mixer.

could be alot of things, do you have a complex or simplex system?

There's a filter on your LPG line? How wouldn anything get into the lines.

Check that the tap on your tank isn't almost shut.

What you are experiencing is usually caused by low gas pressure.

Usually Either it has a faulty gauge and you are almost out of gas or your gas filter is blocked. The gas filter is loacated underneath the gas lock off in your engine bay, its a seperate lock off solenoid usually not far from the converter, some are actually mounted on the converter. It looks like a bowl underneath the lock off solenoid with a bolt going through the bottom of it. You undo the bolt and check the filter and replace if necessary.

But make sure you turn the gas valve off at the tank and run the car on gas until it stops first. Otherwise you will have a heap of pressurised gas escape when you undo the filter and you may get burnt. It is usually left to a specialised gas fitter to play with as the high pressure side of the gas system can be dangerous if things arent done right.

But if i was you the first thing id do is go put gas in it and go from there.....

yes there probably is a filter on the main lockof from the tank.

you can get shit in your gas line exactly the same way you can get shit in your fuel tank.
what happens if your LPG filler point is full of mud?
