Special couplings require special handling. You can’t just unplug a fuel line or an air conditioning line like pulling an electrical plug from a socket. You risk damaging the unique coupling mechanisms and could cause a leak, or they could disconnect unexpectedly. The Powerbuilt 12 Piece Fuel, Transmission, and Air Conditioner Line Disconnect Kit is an innovative kit designed to easily separate fittings found on A/C, filter, transmission, and fuel tank disconnect lines without damaging the line’s delicate coupling mechanisms. Versatility is built into the kit as it works on late model Ford, GM, and Chrysler vehicles. The kit includes 12 line disconnect tools and replacement rubber bands. The 4 quick disconnect tools are color-coded by size to help quickly find the correct sized tool for a specific vehicle. The set comes in a heavy-duty carry case with usage photos and detailed instructions.
