Being natural, it does not lead to any harmful emissions. However, there are certain disadvantages that need to be considered while opting for natural gas as a substitute for artificial fuels. What are the disadvantages of natural gas?
you may be having a problem with your gas sender.
yes a fuel filter problem can cause a starting problem because if your fuel filter blocks the gas wont flow through and you wont get gas to the pistons to start the engine
The knocking problem you are having is most likely the gas you are using. If you switch to a higher octane fuel it should solve the problem.
running out of gas
Do you think that the choke might be on or the fuel to air ratio might be off?
There would be no problem. That's what fuel tanks are for, As long as the tank was designed and built for the gas (or other fuel) with which you are filling it.For instance, you would not want to try to fill a gasoline tank with liquid natural gas.
Fuel pressure regulator.
The fuel gauge sending unit in the fuel tank is probably the problem.
Low fuel pressure.
You may need to check the path of gas from the tank to the carb. It could be a faulty fuel pump, a clogged fuel filter.
This issue could be due to a clogged fuel filter, a faulty fuel pump, or a problem with the fuel tank venting system. I recommend having a mechanic inspect these components to determine the exact cause of the issue.
I am having the same problem. I had the fuel pump replaced and the problem was solved, but now the car stalls when I make a left turn. the engine light still goes on, but not when the gas tank is full. I suspect something malfunctioning in the gas tank, or in the fuel delivery system itself.
