Best Answer

Undo straps. Remove filler hoses. Unplugs fuel module harness. Take off fuel lines at tank. Remove fuel tank, remove retaining ring on top of tank. Pull out module (sending unit/pump) & replace with new one. Don't forget to replace the "O" ring & retainer ring. Reinstall tank in reverse order and I hope you did some diagnostics because some of these modules are $5-700.00.
