I have been searching for some time on extended fuel tank systems. I have an older 1998 tacoma and found a nice extended tank addon that goes above my spare tire but cannot find anything for new trucks like my 2009 tacoma. I can see several systems for Dodge and Ford that replace the primary fuel tank with a larger one. Anyone seen anything like for the tacoma's? I am looking for either a replacment primary tank with larger than 21 gallon standard capacity or an extended addon tank. Would prefer just a primary as I dont have to add any addtional filler lines.

Thanks!
