Lisle 61130 Diesel Filter Wrench, 8ft - Half-Moon Access Tool

In this review the Lisle 61130 Diesel Filter Wrench is assessed for technicians and DIYers who work on heavy-duty diesel rigs. The bottom line: this 8' wrench is built to give easier access to stubborn fuel filter collars and vent caps on Detroit Diesel DD13, DD15 and DD16 engines, and it stands out for its thick, high strength steel construction that resists flexing while loosening tight fittings. For anyone replacing aftermarket diesel fuel filter systems or servicing Davco-style 8' filters, the wrench delivers targeted reach and a secure grip.

Key Features

• Half-moon design: The unique shape provides easier access around filter housings so technicians can reach collars and vent caps in tight engine bays.
• High strength steel construction: Thick steel reduces flex when loosening stubborn filter collars, giving more controlled torque transfer.
• Four-tooth gripping: Four teeth grab the vent cap securely to help prevent rounding or damage during removal.
• Fits common diesel platforms: Works with Detroit Diesel DD13, DD15 and DD16 engines found in Paccar, Daimler Trucks North America and Volvo applications, making it useful across fleets.
• Davco compatibility: Sized to fit 8' Davco filters and many aftermarket diesel fuel filter systems for direct interchangeability.

Who It's For

The Lisle 61130 is aimed at diesel mechanics, fleet service shops and experienced owner-operators who need a dedicated tool for main filter collar and vent cap removal on heavy-duty engines. Its construction and shape suit repeated service tasks and tight engine compartments where standard wrenches struggle.

Those who should look elsewhere include casual homeowners or light vehicle owners who do not service diesel heavy-duty engines, and anyone needing an adjustable multi-fit strap wrench for a wide range of filter sizes; this is a purpose-built 8' tool rather than a universal filter wrench.

Pros & Cons

Pros

• Sturdy, thick steel offers good resistance to flex and feels durable in use.
• Half-moon design and 8' length provide better access to collars and vent caps in confined spaces.
• Four teeth secure the vent cap and help prevent damage during removal.

Cons

• Fit is mixed for some users; while many find it perfect for Davco-style 8' filters, a few report it is not an exact fit on every aftermarket collar.

Specifications
