Welcome from Oklahoma, Native America!New to forum and I couldnt figure out how to post in correct forum. I got a 2014 1300 vstar that is leaking fuel through overflow tube while sitting in hot weather. Whats the problem?
Probably won't do any good to clean the overflow tube, but cleaning the tank vent might. On my V-Star the vent is an orange rubber or silicone nipple at the base of the hinge under the gas cap (may not be configured the same on a Raider). I just sprayed carb cleaner in and around the nipple to make sure it was flushed out completely. The plastic hose that comes with the can is just the right size to fit down inside that nipple.Its not affecting my mpg as i avg around 43. I do tend to top off my tank though. Should i just spray the carb cleaner directly in the top of of the overflow tube to clean it?It looks like it has some sort of filter about half way down sitting on top of the radiator.
Patrickdk is precisely right, the vent should have nothing to do with the pressure build up - it is designed to allow air in to the tank so that fuel can flow unrestricted into the subtank and fuel pump. I should have thought that response through a little better!My guess would just be the gas is doing what gas does when it gets hot, and creates more vapor.
Then it's condensing in the overflow hose back into a liquid.
Not sure how the vent would apply, as the vent is meant to allow air into the tank, as you drain it. Though I do wonder how the overflow is setup, probably is at the bottom of the tank and runs to the top, and the vapor pressure is pushing it out, not much you can do about that, if that is how it's made.
