Larger fuel tank for seadooo trixx

anyone know of any larger fuel tanks for the seadoo trixx ? ive searched the web and don’t see much. maybe seadoo will come out with something. i don’t want the back kit but id like a bigger tank to replace the stock one. there’s tons of room. i may have to build one out of aluminum but I’d rather plastic one that is built specifically to hold the filler in the right place and hold the sending unit properly, etc.
