  Q: How to Replace a Fuel Filler Hose on Cadillac Seville?

  A:

  Streaming the Fuel Tank should be performed to drain it down past the Fuel Filler Hose level. You should lift the vehicle to access the wheel house filler pipe opening cover after draining the Fuel Tank below the hose level. Before you can detach the fuel filler pipe you need to first loosen the ground wire bolt for the tank filler pipe as well as the fuel filler pipe clamp. The first installation step involves putting in the fuel filler pipe with attention to fastener notice in service precautions. Install the fuel filler pipe clamp afterward and secure it with 4.2 n.m (37 lb in). Fasten the Fuel Tank filler pipe ground wire attaching bolt to 9 n.m (80 lb in). To complete this repair the installer should add fuel to the tank only after lowering the vehicle. The installation process begins with the wheel house filler pipe opening cover. Follow these steps to check for fuel leaks by turning on the ignition for 2 seconds then shutting off for 10 seconds before turning the ignition on to search for fuel leakage. Begin by attaching the Fuel Tank filler pipe cap and negative Battery Cable. The last task involves fuel injector sight shield installation.

  Q: How to service and repair the fuel filler hose on Cadillac Seville?

  A:

  Service or repair operations on the Fuel Filler Hose need to start with fuel system fuel pressure relief through the use of the fuel pressure gauge (J 34730). The first step is draining the Fuel Tank and implementing vehicle lifting procedures before increasing the vehicle height. You must first remove the exhaust system together with the wheel house filler pipe opening cover to reach the Fuel Tank filler pipe. Work to detach the Fuel Tank filler pipe ground wire strap bolt before taking out the fuel feed along with fuel return and evap pipes next to the Fuel Filter and the evap pipes and retainers at the evaporative emission canister. The technician must disconnect the Fuel Tank electrical connectors along with removing Fuel Tank bolts from the Fuel Tank straps to pull out the Fuel Tank from the vehicle for placement in the work area. The Fuel Tank requires disconnected filler tube clamp and fuel filler tube removal. Start installation by fixing the Fuel Tank filler tube to the Fuel Tank before you install the tube and secure the clamp at 4 n.m (35 lb in). Position the Fuel Tank with help before you install the Fuel Tank straps while tightening the strap bolts to 48 n.m (35 lb ft). The installer should replace rear suspension support assembly bolts and Fuel Tank electrical connectors and install evap pipes and retainers together with fuel feed and fuel return pipes and evap pipes near the Fuel Filter. The installation requires tightening the Fuel Tank filler ground wire to 9 n.m (80 lb in) while securing the Fuel Tank filler pipe attaching screw. Reinstall the wheel house filler pipe opening cover while placing back the exhaust system then lower the vehicle. Begin adding fuel before putting on and tightening the Fuel Tank filler pipe cap while reconnecting the negative Battery Cable and performing a fuel leak check as described in the instructions. Last, fix the rear seat cushion to the engine while using the intake manifold sight shield which requires 3 n.m (27 lb in) torque when tightening the intake manifold shield nuts.
