Is it true that this generation of Suburbans has no service-able fuel filter? I just can’t find a part for my 2011 Suburban 2500. 
 

Thanks!

Federal emissions requirements includes vapor emissions from the gas tank and to eliminate it MFR's were required to go to returnless fuel systems to avoid circulating fuel and heating it up. Returnless systems in GM vehicles starting in or around 2003 eliminated the line fuel filter and added a larger lifetime of the pump filter since the fuel isn't circulated anymore. There are millions of vehicles all over the U.S using this system and many get 20000+ miles on a pump.

In Justin's case that would be pump in the plural!  He has 2 fuel tanks and 2 pumps.

Yessir!  The second tank is above the spare tire, it is 11.4 gallons and the main is 26 gallons.  Moving fuel between them is fully automated.

 

Good luck with it, they are great trucks!

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.

      Wiring Help, Please

      By Core-Lokt · Posted

      I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
