I bought a stainless tank from this guy on E-bay. I dont know how he sells them so much cheaper than anyone else. Im very happy with it thou. It fits, works, and looks great. I would run all stainless fuel lines, tank, and sending unit if you can. Todays fuels are really low quality... http://www.ebay.com/itm/1969-FORD-MUSTANG-STAINLESS-STEEL-GAS-TANK-NEW-/230557051538?pt=Vintage_Car_Truck_Parts_Accessories&hash=item35ae456a92
