My car has been sitting in the garage for over 8 years with old fuel in the gas tank. I like to drain and fill it with fresh gas before I start the car after so many years, I tried to siphoned it out but it did not work. I am thinking to disconnect the fuel lines in the engine bay and turn on the fuel pump to collect the old fuel without starting the car. The question is how can I do that. I will appreciate this help very much..
