I have a brand new IMS GasGas oversize 3.4 gallon tank that I bought to fit my 98 250EC, which I never installed. About two months after I purchased the tank I found a 2003 250EC, hence I do not need the tank. The tank has never been mounted and I believe it will fit GG models up to 1999. It also comes with a new set of shroud screws (from IMS). The tank has been in my storage unit for a few years in a box, which I forgot about. These retail for $275 on the IMS website. Make me an offer.
