I have an old (1988) Polaris Trail Boss that was leaking gas from a cracked hose that is attached to the carb. I'm not talking about the fuel line hose to the carb. from the gas tank. I replaced the hose, but I am still having some trouble with it. According to the Polaris technical manual, there is a hose that supplies the gas to the carb. (no problems there) and another that acts as a vent. No other hoses are mentioned or shown in the diagrams. But, there are more hoses than what is shown. One hose runs from the right side of the carb. on the top half of the carb. (looking from the back of the ATV forward), and it connects to a hose on the bottom of the carb via another hose with a "T" fitting. Another hose runs to no where off of this "T" with what looks like a filter on it. The carb. is a Mikuni model VM300SS. A look at Mikuni's web site does not show the additional hoses in the on-line service guide. Is there any one familiar with this set up that can advise me on the proper way these hoses should be hooked up and what may be causing the fuel to still leak? I really can't afford to spend the outrageous bucks that the Polaris service department charges in my neck of the woods at this time. Thanks in advance!!!
