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 special internal coupling mechanisms and could cause a leak, or they could disconnect unexpectedly. The Powerbuilt 6 Piece Master Disconnect Set is an innovative kit designed to easily dethatch fuel lines from fuel filters and between automotive air conditioning lines and their components without damaging the line’s delicate internal mechanisms. The kit includes 6 fuel and A/C line disconnect tools and replacement rubber bands. The line 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.
