The fuel lines on the 1997 Honda Civic run from the fuel tank to the engine. The lines are held in place by clip-and-screw assemblies that must be removed before the lines can be replaced. The lines themselves are either steel tubing or flexible hose. Replacement steel tubing must be welded steel tubing that meets Honda’s specifications. Flexible hoses must be equivalent to the hoses originally installed due to the high pressure in the fuel system.
Relieve the pressure in the fuel system by placing rags on the fuel fitting on top of the fuel filter and using the open-end wrench to hold the fuel fitting and the closed-end wrench to turn the banjo bolt. Slowly loosen the banjo bolt one full turn and allow the fuel system pressure to bleed off. Then remove the bolt.
Remove the clip-and-screw assemblies that hold the fuel line(s) to be replaced.
Disconnect the fuel line(s) to be replaced. Disconnect flexible hoses from steel tubes by loosening the clamps using a screwdriver.
Install new fuel line(s) using new O-rings at threaded fittings. Reinstall clamps that were removed.
Reinstall the clip-and-screw assemblies to hold the fuel line(s) to the underbody. Check to ensure that no fuel line is located closer than ¼-inch from the underbody. Also check that no fuel hose is within 4 inches of any exhaust system component or nearer than 10 inches from the catalytic convertor.
Install new sealing washers at the banjo bolt and tighten the bolt to 25 foot-pounds. Start the engine and check the fuel system for leaks.
