Carburetor and Fuel Pump Kit for Polaris Sportsman 500 HO 400 450 335 700 600

This carburetor and fuel pump kit rebuilds the fuel delivery system on Polaris Sportsman 500 HO, 400, 450, 335, 700, and 600 ATVs by replacing the carburetor and pump together.

Overview

This carburetor and fuel pump kit gives Polaris Sportsman owners a complete fuel delivery refresh in one package. The carburetor meters air and fuel to the engine while the fuel pump keeps steady pressure from the tank, so replacing both at once avoids mismatched wear. It suits riders servicing a high-hour ATV or chasing a rough-running motor back to health.

Specs At A Glance

Good To Know

Q: Do I need to rejet the carburetor after installing this kit? A: The carburetor ships with stock-style jetting intended for a factory machine at normal altitude. If you run an aftermarket exhaust or ride at high elevation, adjustment may be needed.

Q: Can I install the carburetor and pump separately? A: Yes, each part installs on its own, but replacing both together is recommended since worn pumps often mask carburetor symptoms. Check fuel line condition while you are in there.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
