redsoldblue51, although it might not be necessary or overkill I think it is well worth the money to clean and put the liner stuff in it. I have done several and they still are good after 10 years..... and yes, I learned the hard way. I cleaned several and yet ended up some time later on the side of the road changing fuel filters...
Just my .02 and its better to be a penny wise than a pound poor.
