The heartbeat of your Suzuki EFI system is steady fuel pressure, and the Regulator Assembly 15760-87L00 keeps it rock-solid. Tuned at the factory for DF70A, DF80A, and DF90A outboards (2009-2013), this compact unit meters flow to a precise 43 psi so injectors deliver the perfect mist at idle, mid-range, and wide-open throttle.

Housed in a nickel-plated steel body, the regulator’s stainless spring and diaphragm shrug off ethanol blends and salty splash. Dual Viton® O-rings seat firmly in the rail, creating a leak-proof seal you can trust on long, lumpy runs. Installation is straightforward: pop the retaining clip, pull the old cartridge, press this one home, and click the clip back in place—no special tools, no drama.

Why this OEM part belongs in your spares kit

• Exact calibration: maintains 43 psi (3 bar) for crisp starts and smooth acceleration.

• Corrosion-ready build: nickel plating and stainless hardware resist rust in harsh marine environments.

• Plug-and-play fit: drop-in replacement for rail P/N 15760-87L00—no adapters or tuning required.

• Ethanol-safe seals: Viton O-rings remain pliable, preventing seepage and vapor lock.

Swap it during your 300-hour service and keep your Suzuki purring, no matter how far the next reef lies.
