• Q: How to replace the primary fuel tank module on 2003 Cadillac CTS?

  A: The first step to change the primary fuel tank module starts with disconnecting the electrical connector and fuel tank hoses from the module. Use the Fuel Tank Sender Wrench (J 45747) to turn the cam lock ring counter-clockwise yet keep the tool safe from the fuel pipes. The primary fuel tank module can be accessed for the transfer tube when you lift it upward just enough after removing the cam lock ring while remembering the module turns from horizontal to vertical during removal. Remove the transfer tube from the primary fuel tank module through the procedure of first unlocking the locking mechanism and pulling out the tube. Pull out both the primary fuel tank module together with its seal before discarding it for replacement. Mount a new primary fuel tank module seal onto the module while directing its seal bead towards the fuel tank. To install the module you should grasp its transfer tube from within the fuel tank then align the module near the opening while attaching the transfer tube to the module. The primary fuel tank module needs to be carefully placed inside the fuel tank after making sure that the fuel level float remains free of any binding interference. Press the module downward to align it with the encapsulated ring. Then position the cam lock ring to the fuel tank before rotating it clockwise using the Fuel Tank Sender Wrench (J 45747) until it becomes fully seated while maintaining distance from the fuel pipes. Use the electrical connector to establish power with the primary fuel tank module and replace the fuel tank hoses.
