This is my first post so i hope it works . I'm working on a 2000 lt80 and its dumping gas bad . Theres two lines coming out of the petcock and fuel comes out both lines . One was going to the carb and somebody had the other line capped off . Is this other line supposed to go to the carb ? Is it a vent or a vacume line and shold fuel be coming out of this line or is the petcock messed up ? Any help would be greatly appreciated . Thank alot .
