According to “Cycle Specs” your Drifter 1500 has a total capacity of 5.0 US gallons.Anyone know for sure what size gas tank my 1999 Vulcan Drifter 1500 has? I thought 5 gallon, but I've never pumped close to that into it. I would try to swap for a bigger tank, but mine looks so good I hate to redo it: View attachment 260095
