Been searching for an answer for hours. I have a 95 yj, I need to replace my stock gas tank skid. I keep finding 15 gal skids for cheap and 20 gal tanks for four times as much. What I can't figure out is what size I have. From what I read all yj's have 20 gal tanks but some only take 15 gals due to a short vent tube. I just need to know what i have without dropping the tank.
