Does anyone know about these fuel pumps? I have a 2003 sportsman 600 that I posted earlier threads about my troubles with it getting hot and quitting. I’ve rebuilt the carb and ruled out air and spark. I replaced the little white fuel filter with a clear one and noticed after it runs and dies after about 20 minutes, the filter is empty. If I pull the line to the carb off, vacuum is restored. I plug the line back in and it’ll run fine for another 20 minutes or so. The vacuum line seems to be delivering plenty of vacuum to the pump. I pull the pump apart and cleaned it, very dirty inside. Put it back on with no change. I have a new pump on the way. I’m wondering if something else internally could be causing my vacuum loss or if it’s likely the pump. I’m very excited that I may have found my issue and hate playing the waiting game. On a side note, it seems that polaris should have put the filter between the tank and the pump rather than after the pump. I’m going to put another filter there in hopes that it helps.
