  Q: How to service and repair the fuel filler hose for a single tank on Chevrolet Avalanche 1500?

  A:

  First for single tank Fuel Filler Hose repairs start by cleaning the fuel pipe connections along with their surrounding areas to avoid any contaminations. Start the procedure by taking off the fuel fill cap with the spare tire stowage lock cylinder and spare tire. Secure the vehicle while elevating it before unfastening screws that hold the Fuel Tank filler housing to fill pipe. The rear axle vent hose clip must be opened at the fill pipe for you to detach the hose. Begin by unbolting the fuel fill pipe ground strap and moving on to loosen both clamp attachments between the vent hose and Fuel Tank as well as the fuel fill pipe and Fuel Tank. The instructions state to dispose the fuel fill pipe bracket bolt before removing both components by separating the fuel fill pipe from the Fuel Tank while disengaging the bracket from the frame. Prevent contaminant entry into the Fuel Tank by placing a cap on its open end. Start by uncapping the Fuel Tank opening then install the fuel fill pipe and vent hose to the Fuel Tank while securing the fuel fill pipe bracket to the frame before you install the fuel fill pipe bracket bolt and secure it to 12 n.m (106 lb in). Following Fuel Tank clamp tightening to 2.5 n.m (22 lb in), install the fuel fill pipe ground strap bolt and tighten it to 9 n.m (80 lb in). Reposition the rear axle vent hose clip to the fill pipe before lowering the vehicle while securing Fuel Tank fill pipe screws with 2.3 n.m torque. End the repair process by putting back the spare tire followed by the spare tire stowage lock cylinder and fuel fill cap.
