Look on passenger side frame rail ahead of the rear wheel in a bracket with a fuel line on each end. Before starting replacement-- be sure to release pressure from fuel lines, by removing fuel pump fuse under hood and running engine to use gas from lines. I then remove fuel lines by moving clamps away from fitting so hose can be pulled loose from old filter while it is still in bracket. On top of mounting is a bolt that holds filter clamp in place . After removing clamp and filter from mounting bracket, loosen filter body clamp and slip oout old filter-- then in with the new filter. Then reverse your steps to install filter. After filter is back in place -- reinstall fuel pump fuse, turn on key for a few seconds for gas to refill lines, then start engine and check your installation to make sure you have no fuel leaks at line connections.
