M38A1 fuel tank cleaning?

[Casey B]

here are some pics of the tube i am speaking of It is in very tight and i do not want to wreck it if it is not supposed to come out...You can see there is no real palce for this to go even if i did get it loose unles it folds or over laps to fit through the neck opening? I tried to gently pry where the indents are and nothing...tried a puller on the bottom and like I said am curling the lip over...Any thoughts other than heat and penitrating oil if this pieces does come out?
