I’ve got a 1999 Polaris sportsman 335 and I think I’m having troubles getting fuel to the carb. I traced the fuel lines coming out the tank that go to the 3 way (on, off, reserve) valve and they then go to something I don’t know what the hell is before more lines coming out of that eventually go to the carb. Why Polaris made it so freaking complicated just to get fuel to the carb is beyond me?
Anywho, this "part" that the lines go to has about 6 screws that secure a plate which I decided to unscrew just to figure out what the hell this thing was, has some sort of clear membrane under the plate. This "membrane" separates one of the fuel lines that goes to the carb (there are 2 that go to the carb btw) and there is no fuel in that line. That line is BONE dry. The other line that comes from this contraption flows fuel but the outlet for that line is on the other side of the membrane. What the hell is this membrane and fuel line for if there is no fuel getting past it? Is this some sort of semi-permeable filtration membrane or what? Please help!!! Every other small engine I have worked on is straight forward with a single line coming from the tank that goes through a shut-off valve, through a in-line filter and to the carb. WTF is Polaris’s deal with all this other mumbo-jumbo?
