What year is your truck? My truick has the same problem and have tried to get Nissan to pay for it. Nissan dealer said that the recall was never performed but it is too old and does not qualify. This is BS. It is a safety issue and should have nothing to do with age ( 2000 Frontier SE). Any ideas on how to pursue before doing it myself? How difficult is it to pull off the truck bed? Was your gas tank rusted?
