I'm about to have a new gastank put in my car because no matter how I try all the methods, I can't pump gas in tank. Pump turns off quickly. So I tried putting gas in from a container thinking it was a pressure problem. That works. Fiat dealer says if they use pressure pump to clear it, it would only last a week. Design flaw in these tanks which makes filter clogged after so many yrs. Now it will cost approximately 1900 to replace tank, parts and labor. Anything else can they do instead of replacing tank?
