A compact, complete fuel line disconnect removal tool set that makes separating quick-connect fittings fast, safe, and repeatable — ideal for fuel, A/C, heater and some automatic transmission line work. Key benefits Saves time and reduces frustration: multiple sizes let you match the connector the first time without improvising or damaging fittings. Protects components: molded plastic edges avoid metal-on-metal contact that can scratch or gouge plastic or plated fittings. Organized and portable: all 16 pieces fit in a transparent storage box for easy transport and on-the-bench access. What’s included 16-piece set: seven opening sizes — 1/4", 5/16", 3/8", 1/2", 5/8", 3/4", 7/8" — plus 2 valve core wrenches. Clear plastic storage case for neat storage and quick selection. Material and build Made from high-quality hard plastic designed for strength and stiffness. Resists rust and corrosion; lightweight for improved handling in tight spaces. Function and ease of use Angled design and compact profile let you reach connectors in confined or awkward locations. To use: place the tool notch against the fuel or service line coupling, press to release the internal lock, and pull the fittings apart. Seven sizes provide coverage for a wide range of common quick-connect fittings. Compatibility and performance Designed for disconnecting fittings on: Fuel lines Air conditioning service lines Heater hoses Also works with some vehicles’ automatic transmission lines where quick-disconnect fittings are used. Multiple sizes increase the chance of a proper fit across model years and manufacturers. Practical use scenarios Changing a fuel filter on a late-model car: select the correct size, insert the tool, release the lock, and separate the fuel rail or filter fittings without prying or cutting lines. Servicing an A/C line in a cramped engine bay: angled blades let you access the quick-disconnect behind components and disengage the coupling cleanly. Replacing a heater hose or swapping a transmission cooler line: use the matching size to safely release the coupling and avoid damage that causes leaks.
