This pump is a direct replacement in-tank fuel pump for EFI Polaris ATV/UTV applications. The kit includes a new fuel pressure regulator, as well as the correct OE length strainer to do the job correctly, which ensures the pump does not cavitate or suck air during steep terrain undulations. Quantum's Polaris replacement fuel pump kits are specifically designed to withstand sustained use in hot climates. The Polaris fuel pressure specification of these models is 39psi +/- 3psi. If your pressure is less than that either at idle or during acceleration, the culprit is likely the fuel pump--an extremely common issue with Polaris ATV/UTV's. Typical fuel pump failure symptoms include stalling, popping, missing under load or acceleration, or intermittent quitting during hot weather operation.
