I wasn't sure where to post this and I've search it a little bit and no one has answered it yet so I'll throw it out there again ! My 05 ranger 2wd 2.3l single cab had a 20 gallon tank is it possible to put that in my current 2001 4x4 extended cab 4.0l ??

 

I've used "Auto Salvage" yards for some cross referencing before. They have a huge database of "what fits what". Try it.
