Q: How do you remove the high-pressure fuel pump for Buick Enclave,Chevrolet Traverse and GMC Acadia?
A: To remove the high-pressure fuel pump, start by disconnecting the cable from the negative battery terminal and relieving the fuel system pressure. Then, disconnect the low-pressure feed line and use a flare nut wrench to unscrew the high-pressure fuel line fittings from the pump and Fuel Rail. Disconnect the electrical connector from the high-pressure fuel pump and remove the pump by unscrewing the bolts. Always replace the bolts and O-ring. Before installing the pump, make sure the camshaft lobe is at its base circle and lubricate the pump roller with engine oil. Install the gasket and bolts. To install the pump, set it into the cylinder head and tighten the bolts evenly to the proper torque specifications. The remaining steps involve reversing the removal process, including cleaning the high-pressure fuel line fittings, applying clean engine oil to the threads, and tightening the fittings to the correct torque specifications. Finally, reconnect the cable to the negative battery terminal, start the engine, and check for fuel leaks.
Q: How do you remove the fuel pump for Buick Enclave,Chevrolet Traverse and GMC Acadia?
A: To remove the fuel pump module in this vehicle, start by disconnecting the cable from the negative battery terminal and relieving the fuel system pressure. Then, remove the Fuel Tank and disconnect the electrical and fuel supply line quick-connect fitting from the fuel pump module. Next, use a hammer and brass punch to rotate the lock ring counterclockwise and remove it. Carefully pull the fuel pump module out of the tank, angling it as necessary to protect the fuel level sensor float arm. To remove the fuel level sensor, push down on the retainer to release it, and then disengage the wiring terminals and replace the fuel level sensor. Finally, inspect the O-ring and replace it if necessary. The installation process is simply the reverse of the removal steps.
