I purchased a used IMS 3.1 gallon from a guy on craigslist. This is my first oversize gas tank and I have a question. On this used tank there is a small 1/4 inch plastic hose that connects both sides of the saddle tank. The hose was broken when I purchased it. I slid a piece of rubber hose in its place to trial fit the tank. The hose runs dangerously close to the exhaust pipe. Is this a factory part. There are brass elbows on both saddle halves. I am now questioning if this is factory? Looking on the IMS website, they do not show any hose on any of there tanks. Does anyone know anything about this?
