Lisle Disconnect Pliers 37140 45° Low-Profile Fuel/EVAP/DEF Line Tool — Slim Head for Tight Spaces

Lisle 37140 Disconnect Pliers are a low-profile, 45° bent tool engineered to release fuel, EVAP and DEF line fittings in tight spaces where standard pliers won’t reach.

When you're working around crowded fuel tanks, EVAP canisters or diesel exhaust fluid connections, access and leverage matter. The Lisle 37140 was designed to slide into narrow gaps and depress two-tab style fittings so connectors separate cleanly without forcing or damaging lines. Its angled head and slim profile make it a practical choice for professional technicians and DIYers dealing with cramped underbody or engine-bay assemblies.

How does the 45° bend make removal easier?

The angled head aligns with connectors tucked beneath tanks or behind components, giving you a natural wrist position and more clearance than straight tools. That geometry lets you reach fittings that would otherwise require removal of surrounding parts.

• 45° offset places the jaws parallel to hidden tabs for reliable engagement
• Slim profile fits between tank top and vehicle structure
• Improves leverage while reducing hand fatigue in confined jobs

Which fittings and connectors is this compatible with?

This plier is optimized for many two-tab fuel line disconnects, common EVAP and DEF quick-disconnect fittings, and some electrical connectors that use press-tabs. It works particularly well on Delphi-style two-tab connectors and many import vehicle fittings, though compatibility can vary by model and year.

• Designed for two-tab fuel and EVAP line quick-disconnects
• Suitable for many DEF line fittings that use depress tabs
• Can be used on some electrical connectors with similar tab layouts

What advantages does the low-profile design provide?

The thin, low-profile body lets the tool slide into tight clearances where bulkier pliers or disconnect tools cannot. That means fewer parts to remove, faster service times, and reduced risk of scratching or bending nearby components while you work.

• Fits narrow gaps under fuel tanks and behind assemblies
• Reduces need to dismantle surrounding parts for access
• Protects adjacent hoses, connectors and vehicle surfaces

How should I use the Lisle 37140 safely and effectively?

Position the jaws so they depress the connector tabs evenly, squeeze to release, and pull the lines apart while keeping the tool steady. Use light, steady force—if a connector resists, check for secondary locks or retaining clips before applying more force.

• Ensure vehicle is stabilized and pressure released where applicable
• Locate both tabs and align jaws squarely to avoid slippage
• Inspect connectors after separation to confirm seals and fittings are intact

Who is this for?

The Lisle 37140 Disconnect Pliers are aimed at mechanics, fleet technicians and informed DIYers who need a compact, dependable tool to service fuel, EVAP and DEF fittings in restricted spaces. If you frequently work on vehicles with hard-to-reach quick-disconnects or prefer tools that reduce disassembly time, this angled low-profile plier is a useful addition to your toolbox.
