The tank has an air vent - generally a pipe or a small hole in the filler cap to permit air in because the tank empties. A number of the latest devices Use a carbon filter
Stay current for security recalls Which may impact your motor vehicle, Enroll in alerts and we are going to e mail you once they get declared.
The two are desired for an exact prognosis, but checking fuel process tension which has a mechanical gauge is the most rational area to start out.
