Fuel Pressure Regulator for Yamaha ATVs
This Quantum HFP-PR335 fuel pressure regulator fits multiple Yamaha models including the Grizzly 700 from 2007 to 2020 and the Kodiak 700 from 2016 to 2020. It also covers the Raptor 700 from 2006 to 2020 and the Viking 700 from 2014 to 2020. The transparent housing allows visual inspection of internal components.
Direct replacement installs with basic hand tools
Installation follows the original equipment layout so no fabrication or specialised tooling is required. The most common issue is residual fuel pressure in the line; relieve it before disconnecting the old regulator. Verify the mounting surface is clean and the O-ring seats evenly to prevent leaks after reassembly.
Confirm exact model and year before ordering
Check the vehicle identification tag against the supported list: Grizzly 550 2009 to 2014, Grizzly 700 and Kodiak 700 2016 to 2020, Raptor 700 2006 to 2020, Viking 700 and Viking VI 2015 to 2020, Wolverine and Wolverine X4 2016 to 2020. This regulator does not fit models outside those ranges or other manufacturers.

Questions about this item
How can I verify the regulator is delivering correct pressure after installing it on my 2016 Yamaha Grizzly 700?
Connect a fuel-pressure gauge to the rail; the engine should hold steady pressure at idle and under throttle without fluctuation or drop-off.
What comes with the HFP-PR335 and what must I supply myself?
The package includes the regulator unit only; you will need fuel line, clamps and a compatible pressure gauge for installation and testing.
Which version of this regulator fits a 2018 Yamaha Wolverine X4?
The HFP-PR335 is listed for the Wolverine X4 (YXF85) 2018, so this single part number covers that model year.
