ALL BALLS Fuel Pump Repair Kit for YAMAHA WR 250, WRF 450, YFZ 450, YZF 250, YZF 450 2008-2025

ALL BALLS offers this fuel pump for YAMAHA WR 250, WRF 450, YFZ 450, YZF 250, YZF 450 2008-2025. On fuel-injected bikes, an electric pump inside the tank sends pressurised fuel to the injector as soon as you switch on the ignition.

Why replace the fuel pump?

The benefits:

• Get back an engine that starts easily and pulls all the way to the top of the rev range.
• A rebuild kit restores the original module without buying a complete new one.
• Avoid breaking down far from the van: a tired pump often fails without warning.

Why choose ALL BALLS?

Complete All Balls kits: low-friction bearings and steel-spring nitrile seals, everything you need in one box.

When should you replace this part?

An engine that stutters or cuts out at high revs, hard starting, a pump you no longer hear when you switch on, or a leak at the pump: check it and replace it if it is at fault.

Specifications and fitting tips

• Restore lost performance of non-functioning fuel pump with this economical solution.
• Kits come ready for plug-and-play installation.
• Manufacturer part number: 47-2037

Cross-Mania tip: Work with the tank nearly empty and, on an electric pump, the battery disconnected; replace the seals and filter at the same time and check the connections for leaks before starting.
