Codes FET 611 PO 4550

Code from iCarsoft - FET 611 fuel tank large leak PO4550
Anyone have any ideas?

Also for trans AT 143 kickdown switch signal. Perm fault too low.

All started with flashing arrow....trans worked fine then only engine rev.

Replaced PNP, ABS MODULE, cleaned wheel speed sensors. Still flashing arrow. I bought the iCarsoft i906 code reader to further investigate if there were other more serious transmission codes . I am doubtful that a kickdown cable or switch will rid the arrow or no power permanently.
Not sure what to do next. I don’t want to put anymore into this car. 98 V70 Xc
