I have a 95 Lexus SC400.. Im Really trying to figure out a price range on a new and/or used fuel Tank & im not sure where to start looking other than locally or even ebay. Ive found used tanks on Ebay for approximately $125-$200 but I cannot find any websites that sell new tanks.. I need help because I am new on this whole having my car fixed situation in which I really need my car Fixed ASAP & I want to be somewhat educated/informed before I go out and have a mechanic charge me an arm & a leg for a part that could otherwise be bought at a cheaper price. Anybody have any information on websites, experiences, knowledge & what have you they would be Greatly Appreciated! Thanks. :D
