    Does anyone have any idea where the FPR is located on a 2005 yukon xl 5.3L flex fuel? I have looked at a few sites that say it is incorporated into the fuel sending unit. Thanks

    Sorry I took sometime in getting back to you Mike......I was looking for good photo of the Fuel Pressure Regulator.......On a 2003" 5.3 Liter Flex Fuel Engine......The Fuel Pressure Regulator, is on the upper Driver's Side portion of the Engine, directly below the Plastic Intake Manifold Shroud...it should be in the same location on your 2005" 5.3 liter.....

    Well, I checked again. Referred to my manual for my 02 silverado again also. I see the spot were it should be, but it is just a junction no regulator there. In 05 they also put the fuel filter in the tank for the first time on this truck. So, maybe they did the same with the regulator

    Mike....Interesting???.....the photo of the Reg. from Rock Auto....it's for a 2005" GMC Yukon XL 1500, with a 5.3 liter.

    Also from Rock Auto, Regarding the Fuel Pressure Reg.....It expresses the following:....Please check notes in each part listing to ensure the Fuel Injection Pressure Regulator is correct for your 2005 GMC YUKON XL 1500 with a 5.3L engine. Special restrictions like "California only" or "with sport package" may indicate a Fuel Injection Pressure Regulator fits only certain 2005 GMC YUKON XL 1500 models.

    Edit.....Mike, I'm going to do some research on this, and I'll get back to you.

    Mike.....Here are the Fuel Rails, from a 99" to 2000" and from a 2005" to 2006"....both show what Engines/RPO Codes these rails are for....

    Chevy 1999-2000 CK1, 2, Fuel Injector Rail, (LM7/5.3T, LR4/4.8V, LQ4/6.0U)....Number #9 is the Fuel pressure Reg.

    Of course, you went above and beyond. I now have my answer. I have an L59 engine. No regulator on the rail. Damn you GM, you took away my ability to change the fuel filter and the regulator!!!:grrrrrr: Whats next? In a few years am I going to have to go to a dealer to fill it up with fuel!!
