Fuel delivery problems aren’t always dramatic — at least not at first. For many Kawasaki Ultra 310 and STX 160 owners, the early signs are subtle: inconsistent fuel pickup at lower levels, hesitation under sustained load, or a ski that suddenly feels less predictable as the tank runs down. Over time, those small issues can snowball into reliability concerns that affect everything from ride confidence to engine longevity.
A big part of the problem comes down to fuel pump design. OEM pumps often leave usable fuel sitting untouched in the tank due to short pickup placement. Plastic housings can struggle with heat management, especially when fuel levels drop, and smaller, lower-flow pump designs aren’t always ideal for riders who push their skis hard or spend long days on the water. Add in restrictive or easily clogged fuel bags, and it’s easy to see why fuel delivery becomes a weak link.
That’s exactly the problem Kawi Performance set out to solve with its Fuel Pump Mod Kit Assembly for selected Kawasaki platforms.
Designed as a true reliability-focused upgrade, Kawi Performance’s solution rethinks how fuel is picked up, cooled, and delivered inside the tank. The kit uses an original-style pump layout that sits at the very bottom of the tank, helping maximize usable fuel and improve pickup consistency. An extended float arm unlocks additional fuel range that would otherwise go unused, while the aluminum pump housing helps dissipate heat — a critical advantage when fuel levels are low and temperatures climb.
Where OEM setups rely on smaller, plastic-bodied pumps and limited-flow components, the Kawi Performance upgrade emphasizes stronger construction and higher flow capability. The result is more consistent fuel delivery and stable pressure under load, especially in conditions where stock systems can begin to struggle. High-flow fuel bags further improve reliability by reducing restriction and minimizing clogging compared to smaller OEM designs.
Rather than chasing peak numbers or short-term gains, this kit is built around longevity and dependability. It’s aimed squarely at riders who demand their ski perform the same way at the end of a long ride as it did at the beginning — whether that’s aggressive recreational use, endurance riding, or performance-focused setups where fuel stability matters.
The Kawi Performance Fuel Pump Mod Kit Assembly is designed for select models, including:
- Gen 2 Ultra 310
- STX 160
- Ultra 160
By addressing known shortcomings in OEM fuel pump design, Kawi Performance delivers a solution focused on real-world riding conditions — improved pickup, better cooling, stronger construction, and more usable fuel where it counts.
For riders looking to eliminate fuel-related reliability concerns and get the most out of their Kawasaki platform, this upgrade targets one of the most overlooked but critical systems on the ski.
