2004 GMC envoy. Customer requested fuel sending unit to be replaced. Upon speaking with other envoy owners this is a common occurrence in corrosion areas, namely nova scotia. The leak was found after owner smelled a constant gas odor around the back driver wheel well. When the gas tank was taken down for inspection the modular reservoir assembly, which contained the fuel pump, developed corrosion of the fuel fee/return pipes after an extended period of time.
