Magluv Fuel Filter Wrench Set 6in & 8in for Davco-Style Caps — Solid Steel, Rubber Handle

Magluv's 6-inch and 8-inch fuel/filter vent cap wrenches are heavy‑duty steel tools designed to remove and install Davco-style fuel/water separator caps on Detroit Diesel, Navistar and Cummins engines without bending or damaging the housing.

Keeping heavy-duty truck fuel systems serviceable means having the right removal tool for stubborn filter caps. This two‑piece Magluv set includes a 6" and an 8" wrench sized to fit common Davco part profiles used on Detroit Diesel DD13, DD15 and DD16 engines (and many Cummins/Navistar applications). Built from solid steel with a soft rubber coated handle, these wrenches give you leverage and grip for routine maintenance and filter swaps.

Which filter caps do these wrenches fit?

Each wrench is shaped to engage the specific ring and jaw designs used on Davco fuel/water separators. The 6" unit replaces tools used for 380134/382 style caps, while the 8" fits the larger 482/483/782 family commonly found on newer diesel engines.

• 6-inch: compatible with 380134, 382 Davco-style caps.
• 8-inch: fits 482017 and 482/483/485/487/488/782 models.
• Designed for Detroit Diesel DD13, DD15, DD16 and many Cummins/Navistar engines.
• Two-tool set covers most on-road heavy-duty separators.

How durable and easy to use are these tools?

Magluv wrenches are forged from high‑strength solid steel for long service life and resistance to bending under torque. The handles are coated with blue soft rubber to improve hand grip and reduce slippage during removal or installation.

• Solid steel construction resists deformation when loosening seized caps.
• Rubber-coated handles provide comfort and non-slip control.
• Open-jaw design aligns quickly with filter rings for fast engagement.
• Use steady pressure to avoid metal-to-metal gouging of housings.

What safety and usage tips should I follow?

These are handheld tools meant to increase mechanical advantage, not to replace careful technique. Clamp the wrench jaws so they match the ring profile, apply controlled torque, and avoid letting the metal teeth dig into thin housings which can cause leaks or damage.

• Align jaws fully before applying force to avoid slipping.
• Work slowly when filters are tightly seized or corroded.
• Inspect housing for soft spots—stop if the metal starts to deform.
• Pair with proper drain/containment to catch fuel during service.

What comes in the package and how does it save time?

The Magluv set ships with both the 6" and 8" wrenches so you won’t need multiple single-size tools during a service visit. Having the correct match on hand reduces time spent improvising and lowers the risk of damaging housings or replacement filters.

• Package includes two wrenches: one 6-inch and one 8-inch tool.
• Eliminates searching for separate Davco replacement wrenches.
• Saves shop time during scheduled maintenance or roadside service.
• Durable finish extends useful life between replacements.

Who is this for: professional diesel technicians, fleet maintenance crews and owner-operators who service Detroit Diesel, Navistar or Cummins engines and need a reliable, non-damaging method to remove and install Davco-style fuel/water separator caps. If you perform regular filter changes or roadside repairs on heavy-duty trucks, this Magluv two-piece set provides the sizes and strength to make the job faster and safer.
