When your pump struggles to maintain correct system PSI, your engine runs lean, which skyrockets combustion temperatures. \u003cb\u003eInstallation Tip:\u003c\/b\u003e Before cracking open your fuel tank to pull the pump module, wash down the entire vehicle to prevent dirt, dust, and sand from tumbling into the open gas tank. Take your time when extracting the old plastic module assembly. When mounting the new fuel filter strainer and internal hoses, verify that all ear-clamps are squeezed perfectly tight to prevent internal pressure drops. \u003cb\u003eMaintenance Advice:\u003c\/b\u003e Lubricate the main tank-to-pump sealing O-ring with a tiny smear of clean grease or fuel before final assembly to guarantee an airtight, leak-free seal. Always check that the internal tank is clear of any resting rust or sediment before inserting your freshly rebuilt unit.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eKit Classification\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eColor \/ Finish\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003ePrimary Fitment\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eFuel Pump Module Rebuild Kit\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eBlack \/ White Elements\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003ePolaris RZR 170 EFI (2009-2020)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eIncludes Pump, Filters, Hoses, Harness\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eDirect OEM Mechanical Fit\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eYamaha YFZ450R \/ YFZ450X ATVs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eRiding Style: ATV \/ UTV \/ Off-Road\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003ePlug-and-Play Assembly\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eYamaha YZ250F \/ YZ450F \/ WR \/ XT Bikes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFAQ Questions\u003c\/h3\u003e\n\u003cp\u003eQ) \u003cb\u003eDoes this kit include the main outer plastic housing structure for the fuel pump module?\u003c\/b\u003e\u003cbr\u003eA) No, this kit is specifically engineered to replace the wear-and-tear internal components (the core pump, filter strainer, internal wiring, and fuel delivery lines) inside your existing factory plastic housing frame.\u003c\/p\u003e\n\u003cp\u003eQ) \u003cb\u003eWill this kit work on older carbureted models or only fuel-injected (EFI) machines?\u003c\/b\u003e\u003cbr\u003eA) This rebuild configuration is designed strictly for high-pressure Electronic Fuel Injection (EFI) systems and fits the specific fuel-injected Polaris and Yamaha off-road models highlighted in our fitment directory.\u003c\/p\u003e\n\u003cdiv class=\"silo-links\"\u003e\n\u003ca href=\"\/search?q=Yamaha+and+Polaris+Fuel+System+Components\"\u003ePowersports Fuel Systems\u003c\/a\u003e | \u003ca href=\"\/search?q=ALL+BALLS+RACING+Fuel+Pump+Rebuild+Kits\"\u003eShop All ALL BALLS Components\u003c\/a\u003e | \u003ca href=\"\/search?q=ATV+UTV+and+Dirt+Bike+Engine+Management\"\u003eFuel Management\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003eMoto-House MX – Choice of Champions\u003c\/b\u003e – is located in Clermont\/Montverde, FL.
