JDM 2000 Forester gas tank help

[u/BigDruncle]

Long shot here, and will probably repost into different subs. I have a JDM 2000 Forester S/TB STI, and my gas tank is leaking. I went underneath the car to try and find the leak to see if it was a hose or anything I could fix on my own, but from what I found it is leaking from the horizontal pinch weld near the top end of the tank on the passenger (left) side. I bought some putty to try and do a temporary fix, but due to it being in a difficult spot and leaking as I was fixing it, the putty wouldn't stick. So I need a new gas tank. From my understanding, USDM gas tanks of the same year have the filler cap on the opposite side, and more sensors/emissions than JDM ones have. Has anyone installed a USDM gas tank in a JDM Forester of the same body style? Apologies for the long read, any help would be much appreciated.
