My car started riding rough yesterday, the pick up was bad. I don't know why but I checked the gas cap just to make sure it was on properly and a whole bunch of air came out. Can anyone explain this. Should I be worried and is it dangerous?Its possible the fuel expanded when it warmed up, there is usually a very small vent hole in the filler cap, don't know this car but check that the vent isn't blocked or replace the cap?I suspect there is moisture in your gas tank, an additive can be poured into your gas tank to dry out the water. As far as "air" pressure in your gas tank there shouldn't be any as the gas tank has a vent line. It could be that their is a bit of corrosion plugging the vent line. As far as a fix as I said use an additive to dry up any water in your gas tank and also look into replacing the fuel filter.Are you sure it was air coming out? It sounds like the charcoal canister lines may be unhooked or plugged. If that happens, it creates a vacuum in the tank and when you take off the gas cap, you'll hear an air sound kinda like opening a can of pop. I don't know how you would build up air pressure in there.You need a new gas cap. They are designed to release air pressure as the heated gas and air expands. Your cap is not allowing the gas to escape, or the gas leaving the tank going into the motor is creating a vacuum and making it harder for the fuel pump to pump gas....either way you need a new cap.#If you have any other info about this subject , Please add it free.# |
