Where is the fuel injector on a Polaris ATV?
Fuel passes through the fuel rail on the way to the injector (s) and the rail holds the injectors in place. It has a Schrader valve (bicycle valve) at the end where you can attach a fuel pressure gauge or push the valve in and relieve the pressure from the system. Fuel Injector (s) – Located on the cylinder head.
Where is the throttle position sensor on a Polaris ATV?
Throttle Position Sensor (TPS) – Located on the throttle body and operated directly off the end of the throttle shaft. The TPS works like a rheostat, varying the voltage signal to the ECU in direct correlation to the angle of the throttle plate (engine load).
Where is the fuel filter on a Polaris ATV?
Fuel Filter – Located behind the frame member that is just aft of the radiator cap. A cylinder about 4 inches long and 2 inches in diameter with quick-disconnect receptacles on each end. Fuel passes through the 10-micron element inside.
Are there any problems with the Polaris EFI system?
Having been on this forum for about 2 years now, I’ve asked, read and answered a lot of questions. As Polaris keeps making more machines with EFI, it stands to reason that more and more of the the problems & questions are related to the EFI system, its sensors and electronics.

How does electric fuel pump work on Polaris ATV?
An in-tank electric fuel pump is used to move fuel from the tank through the fuel line and in-line fuel filter. The in-tank fuel pressure regulator maintains a constant system operating pressure and returns any excess fuel to the tank. At the engine, fuel is fed through the fuel rail and into the injectors, which protrude into the intake ports.
