Other Fuel System Hoses Lines/piping, And Fittings problems of the 1997 Plymouth Grand Voyager

Purchased vehicle used a year ago, after 1 fuel fill up service engine light came on and smelled fuel strongly in the back. Noticed raw fuel leaking onto the left rear tire& wheel well. Took to dealer for tests, they found leaks from ldp to the tank at a rubber elbow with a raw fuel leak at the connection between the filler neck and rollover valve. Told we need fuel tank replaced to fix the problem costing more than $700!.
