To facilitate the procedure, it is recommended to perform these steps with an empty fuel tank; if necessary, use a siphoning kit (never use your mouth to start siphoning) to remove fuel. Start by relieving the fuel system pressure and disconnecting the negative battery cable. Access the
Fuel Pump/fuel gauge sending unit and disconnect the fuel lines orelectrical connector. Raise and securely support the vehicle on jackstands. If the tank is empty or nearly empty, siphoning is not required; however, for tanks with a significant amount of fuel, drain it by removing the fuel pump/fuel gauge sending unit and siphoning it through the pump/sending unit hole. For Civic models, remove the driver's rear wheel and wheel well liner, then disconnect and remove the fuel filler neck hose and fuel tank vapor hose, checking for damage. Remove the lower rear cover if equipped. Disconnect the fuel line quick-connect fittings at the front of the tank and remove the fuel tank shield. Support the fuel tank with a transmission jack or a floor jack with a protective piece of plywood, then remove the rear underfloor bar and unbolt the fuel tank retaining straps. If applicable, remove the fuel tank baffle plates, and carefully lower the fuel tank. For CR-V models, remove the driver's rear wheel, left and right vehicle undercover panels, and the exhaust pipe, including the mounting bolts and pipe. On 4WD models, remove the driveshaft. Remove the fuel tank guard and fasteners at the front of the tank. Clean the area around the fuel filler neck hose and fuel tank vapor hose, disconnecting their quick-disconnect fittings. Support the fuel tank and unbolt the retaining straps before carefully lowering the tank. The installation process is the reverse of removal.
