EVRBUL's Fuel Filter Water Cup Separator Wrench is a nickel-plated 40Cr steel tool built to remove and service Yamaha 6P3-WS24A filter cups on 2006–current 4-stroke engines (F150–F350, 2.6L and 3.3L, serial 0406).

When you need a dependable, corrosion-resistant wrench and replacement O-rings for routine fuel filter cup removal on compatible Yamaha outboards, this specific EVRBUL tool and two nitrile O-rings give you a fast, tool-free way to access the fuel/water separator.

Which Yamaha engines and filter cups will this wrench work with?

How is the wrench constructed and why does that matter for marine use?

EVRBUL manufactures the wrench from 40Cr steel and applies a nickel-plated finish to resist corrosion and impacts common in salty environments. The robust material and plating improve tool longevity when used near water and fuel, reducing the chance of deformation during removal.

• Material: 40Cr steel for strength and impact resistance.
• Surface: nickel plating for enhanced corrosion protection.
• Includes two nitrile O-rings resistant to aging and fuel exposure.
• Designed for repeated service cycles without rapid wear.

How do I use the EVRBUL fuel filter cup wrench during maintenance?

Operation is straightforward: feed the wrench through the filter cup tube, engage the cup, then twist by hand to unthread and remove the cup. The design eliminates the need for extra tools, helping you complete filter replacement or inspection more quickly on the boat.

• Insert wrench into the filter cup tube until it seats on the cup.
• Grip and manually twist the wrench to loosen the cup.
• Replace fuel/water separator or O-rings as needed, then reassemble.
• Two spare nitrile O-rings included for resealing the cup.

What comes in the package and what should I check before buying?

The kit contains one EVRBUL fuel filter cup wrench and two nitrile rubber O-rings for resealing the filter cup after service. Prior to purchase, verify that your outboard serial number and the 6P3-WS24A cup style match this tool’s compatibility list.

• Package: 1× fuel filter cup wrench, 2× nitrile O-rings.
