2005 Polaris Sportsman 500 HO Fuel Pump

My best guess tells me that the fuel pump was put there for a reason. I don't know much about these vacuum operated pumps on 4 strokes. I suspect that they may be more of a fuel valve than an actual pump. If that is the case, I don't see why the machine wouldn't run off of the gravity fed fuel from the tank. I would just give it a try and see if it works, I would put a shutoff valve in the line though. I know some two stroke engines, use vacuum operated fuel pumps, but they use the alternating vacuum state/ pressure state of the crackcase to actually pump fuel.

      Hi Everyone,
      I recently purchased a 2005 50cc Polaris Predator for my granddaughter.
      The wiring is a mess. most of it appears to be jumpered out (twisted together).
      I installed a new carburetor. The gas tank was cracked so I found another one on ebay and got that installed. There is no air filter box. I ordered another one but, it has not arrived yet.
      I did get it cranked with the kick start. But, it idles too fast and when you give it any throttle the motor dies off. The more throttle you give it the faster it dies off. It is very hard to start when it has not been running for a while. However, once it has warmed up, it starts on the first kick every time after that.
      I am looking for a little assistance in getting it running better and also a wiring diagram and service manual if possible.
      Thanks in advance....

      I generally use Non Ethynol fuel in all my small engines. I just got back from the gas station and that fuel has really increased in price since last year, I will continue to use it, even though its north of 1.00 a gallon more. That seems minor compared to cleaning and repairing carbs every year. 
      I was just curious as to what others are doing in regard to gas in their quads, i know a lot of the newer ones are fuel injected which shouldnt pose a problem, but i have had lots of problems with rust and jell forming in carbs when using ethynol fuel.

      having an issue with the unit when running under a load up a hill or in high gear, seems like the belt is slipping, there is a clapping sound coming from the primary clutch like it releases and snaps back in. i don't think I should have a noise like that. this is a friends unit and he has already replaced the primary twice with the same result.
      not sure where to look next

      Hi, I am having issues with my TRX350D fuel pump.  It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals.  I have fitted a new pump, fuel cut-off relay and rectifier.  Still nothing!!  The pump runs when attached to a battery.  The engine will start on the choke and the filter fills with fuel but it will  not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine.  Any ideas where to go from here would be very much appreciated!!

      Hi,
      Got a Big Boss produced 2016 YM 2017 that gives DTC 520 285 2 (random)
      What I understand is correlation code for brakesensors, very little information in workshop manual.
      Removed front plastic to discover that no connector was mounted on the brake pressure switch!?
      The only "brake" information seems to come from the micro switch at the brake lever.
      Does anyone know if Polaris does anything special on the 6x6 or had this issue?
