If you’ve spent any time around Kawasaki’s modern lineup, you’ve probably heard the whispers—fuel delivery on some of the newer machines isn’t exactly confidence-inspiring. Now, Kawasaki Performance (KP) is stepping in with a fix aimed squarely at reliability and peace of mind.
Their latest release, the DW Fuel Pump Mod Kit, is designed for Gen 2 Ultra 310, STX 160, and Ultra 160 models—basically anything running the plastic fuel pump housing. And from the looks of it, this isn’t just a mild upgrade—it’s a full rethink of a known weak point.
At the heart of the kit is a DeatschWerks (DW) fuel pump, a higher-quality unit that delivers significantly improved flow while still drawing roughly the same low amperage as the stock pump (around 3 amps). That means better fuel delivery without adding electrical strain—something riders pushing supercharged 310s will definitely appreciate.
Because here’s the rub: according to KP, the factory pump flows just 110 liters per hour—a number that’s borderline inadequate for a supercharged platform and not exactly reassuring even on naturally aspirated machines. Worse, when those pumps fail, they don’t just leave you stranded—they can potentially lean out the engine and cause serious damage.
The DW kit aims to eliminate that risk entirely.
Installation looks refreshingly straightforward, too. The system is designed as a drop-in-style upgrade with no permanent modifications required, reusing select OEM components like the original O-ring (important—KP stresses this is critical for proper sealing). The kit also includes a redesigned housing and adapter to properly fit the larger DW pump.
KP also recommends pairing the setup with their upgraded KP1 fuel pressure regulator, which features a larger discharge opening and a much beefier O-ring to better handle increased flow and prevent blow-by—another subtle but meaningful improvement over stock.
And for those who like a little extra reassurance, the DW pump itself comes backed by a 3-year warranty, reinforcing the idea that this is built for long-term reliability—not just a quick performance bump.
The end result? A fuel system upgrade that’s less about chasing top-end numbers and more about making sure your ski doesn’t leave you hanging miles from the ramp—especially on long-distance rides where consistency matters most.
