• Q: How to replace the secondary fuel tank module on 2007 Cadillac CTS?

  A: The procedure for secondary fuel tank module replacement includes removing the fuel tank with subsequent disconnection of the electrical connector. The Fuel Tank Sender Wrench (J 45747) shall be used to turn the cam lock ring counterclockwise before removing it from the fuel tank. The operator must lift the secondary fuel tank module slightly from its position to gain access to the transfer tube. Remove the transfer tube after pulling the locking mechanism from the module direction. After removing the secondary fuel tank module and its seal discard these items because you should not reuse the seal. To install the secondary fuel tank module begin by placing a new module seal over it before connecting the transfer tube to the module by positioning the module next to the fuel tank opening while grasping the tube from inside. When inserting the module into the fuel tank verify that the fuel level float moves freely. Use the master module bottom section to reach the encapsulated ring while applying pressure to bring the module straight then apply the cam lock ring to the fuel tank using the Fuel Tank Sender Wrench (J 45747) to secure the module tight.
