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

  A: The first step for primary fuel tank module replacement requires users to detach fuel tank hoses and disconnect the electrical connector before proceeding. Before removing the cam lock ring on the fuel tank with Fuel Tank Sender Wrench (J 45747), ensure the tool avoids touching the fuel pipes by rotating it counter-clockwise. Access the transfer tube inside the primary fuel tank module by lifting the module slightly before disconnecting it through the removal of its locking mechanism and transfer tube removal. Newly installed seals need to be placed on top of the fuel tank module with their seal bead pointing in the direction of the tank. Obtain the transfer tube within the fuel tank while moving the module closer to the opening before linking the tube with the module while verifying the fuel level float does not get bound. Put the primary fuel tank module into the fuel tank while depressing it to match the ring slot. Then position the cam lock ring before tightening it clockwise using the Fuel Tank Sender Wrench (J 45747) until complete seating. Reconnect the electrical connector of the primary fuel tank module and re-install the fuel tank hoses as the final step of the procedure.
