I have a 97 jeep grand cherokee ltd. this is converted to run on lpg. when running on petrol no problems but as soon as I run on gas i loose power and she runs uneven and drinks the gas very quickly, as in she will only get 6mpg. please help as the fuel price has now reached £7.50 per gallon or $16.00 per uk gallon

Thanks from a newbe in scotland.
Harley Davidson the economicial way of turning gas into noise with out the added effect of horsepower.

 

U may need to change the fuel system out for 1 made for lpg or petrol

 

maybe the lpg carb has a busted diaphram.
