Honda 17045-S3V-A00 Fuel Pump Module Assembly

For these models, you should use a fuel pressure gauge for high pressure. Here are the steps: 1.Disconnect the negative battery terminal. 2.Detach the fuel supply line from the firewall and tee the gauge into this system. 3.After reconnecting the battery, turn the ignition to ON. 4.Check the pressure on the gauge once the engine is at its operating temperature. 5.If pressure doesn't rise upon vacuum line disconnection from the regulator, check vacuum at the hose. 6.If low indicated fuel pressure is observed, inspect fuel lines, consider replacing the fuel filter (integral to the fuel pump/level sending unit assembly), and investigate potential issues like leaking fuel injectors or a faulty fuel pump. 7.After completing the tests, disconnect the battery terminal, remove the pressure test setup, and reconnect the fuel supply line.

For 2001 and 2002 Acura and 2003 and 2004 Honda models, remove the fuel pump access cover screws and disconnect the electrical connector. For 2003 and later Acura and 2005 and later Honda models, peel off the rubber weather seal grommet from the fuel pump access cover and disconnect the electrical connector.

Once reassembly is complete, start the engine and check for fuel leaks at the pump fuel line connections to ensure everything is properly sealed and functioning.
