Suzuki Fuel Pump Assembly – 15100-90J11

If your DF90 or DF115 is coughing at mid-range or taking forever to prime, odds are the original pump is tired. Swap in this complete, factory-built assembly and bring rail pressure back to the 43 psi your ECU expects. Housed in a corrosion-proof stainless can with a molded composite top plate, the 15100-90J11 drops straight into the VST—no shimming, no wiring mods. A precision 40-micron inlet screen and built-in pressure-relief valve keep debris and vapor lock at bay, so cold starts fire instantly and hole-shot hesitation disappears.

Why it’s worth keeping a spare on board

• Direct OEM fit for late-model DF70A/DF80A/DF90A/DF115A four-strokes—plugs into the three-pin harness, uses the stock sealing O-ring.

• High-efficiency turbine design delivers up to 95 L/h while drawing less current than earlier gerotor pumps.

• Stainless body + Viton seals shrug off ethanol blends and salty bilge moisture.

• Rubber isolation sleeve dampens vibration and keeps the pump whisper-quiet at idle.

Install during your 300-hour service and cruise away knowing every injector is getting the steady fuel column it needs for crisp throttle response and peak fuel economy.
