I changed the fuel filter on my 2005 Cadillac STS in under 20 minutes. My car had a slight hesitation but still had power, after the filter change she is smooth as ever. The Cadillac SRX is pretty much the same steps.\r<br>\r<br>Fuel filter \r<br>\r<br>Fuel filter disconnect tool \r<br>\r<br>Spark plugs
