Cadillac SRX Second Generation Forum - 2010+ Discussion, 2012 SRX fuel filter in Cadillac SRX Forums; Hello,
I'm thinking that I should change my fuel filter on my 12 SRX but could not locate it and ...
I would tend to think your fuel filter should be OK ... how many miles are on your SRX?
Most newer vehicles do not have a specified interval for replacing the fuel filter. In fact, some even have "lifetime" filters that supposedly never need to be changed. But any filter can plug up if enough rust or debris gets sucked into the fuel inlet.
Gasoline is supposed to be filtered at the pump. But it sometimes isn't. What's more, the fuel you put in your tank may be contaminated with water from leaky underground storage tanks, improperly mixed alcohol blends, or even watered-down by an unscrupulous operator who's trying to make a fast buck. So there are no guarantees.
If you don't want to replace the filter unnecessarily, you can remove it and check it to see if it passes air easily (More information on replacing fuel filters is available). If the filter creates any significant resistance when you blow through it, it needs to be replaced.
Ok thanks..... Every gm car I've owned in the past has listed regular fuel filter intervals and even provided the AC Delco part number. Since the owners manual makes to reference to the fuel filter whatsoever, I figured I would ask other SRX owners to see what they have done.

While I think this is technically correct, I also believe the fuel filter in the tank is attached to the fuel pump AND CANNOT be purchased separately. Therefore, if changing the fuel filter is your absolute intent, you will need to purchase the ENTIRE fuel pump....for a cost of about $500.
Ok thank you....that's the information I was looking for. I am not going to replace the fuel pump just to replace the filter. My thought was if it was an external filter that was readily accessable I would replace it as part of the routine maintenance.
GM and all MFR's havent used external fuel filters since they went to returnless fuel systems in early 2000's. No filters on the line since the pump only feeds the injectors and there is no return line.
DI engines use two pumps and the primary has the filter in the tank.
I wouldnt worry as the returnless system has a history of 180000+ miles on a pump.
All i can tell you is there IS a fuel filter listed for the 3.6 SRX on both Rock auto's and GM Parts direct website. Boyh sell them for around $23. GM pars direct als lists two fuel pumps. One with an extrnal filter, and one withut and external. This leads me to believe that some SRX's DO have an external filter.
