Swapping fuel tank

Check where made...that’s your major cost difference. More than likely at any of those prices your looking at China as the mfg.. I bought my from Tanks inc. (China) and have had an issue with the shock almost touching the pinchweld. So I rolled it up just a bit to be safe, my tank is a retrofit as I am running fuel injection. Other than the pinch being a little to wide no other fitment issues and good quality for the cost. I think I paid about 250 without the shipping but if you going original you can get it for about 150 plus shipping unless you can get it on eBay and sometimes they ship for free!

Hope this helps!
