I have a 2006 silverado with 47K on it. I was thinking of replacing the fuel filter, but my buddy said it would be pointless with that few of miles. My question to you guys is how often do you change yours?

 

Thanks!

I think after 04, the filters were in the fuel tank and are good for 100,000 miles :cool:

As pointed out, you don't have one that is serviceable. It's in the tank and part of the fuel pump assembly. So you drive until it fails.

 

Edit: I will add that flex fuel models still had an external filter even after all the others had in-tank filters. Just don't know the years right now

The fuel filter was moved to the fuel tank in 04 and is not serviceable with the exception of the flex fuel and the 4.3 V6. The flex fuel was moved to the tank in 05 as I believe was the 4.3 V6. I have seen a late model 05 V6 with the filter in the tank.

 

This was done in conjunction with the returnless fuel system.

So, mine is an 05, and according to a RPO decoding, I have a Flex fuel engine (no badging or any indication anywhere). I should have an internal filter right? Where would it be if it were an odd-ball with an external filter?

Yours should be in the tank and will not be serviceable.

If you had one, it'd be on the inside of the driver side frame rail. On my 03 (reg cab) it was maybe a foot behind the cab if memory serves. Looks just like the one on your Z- silver canister maybe 3" diameter and 4" long.

It's not a filter, only a strainer and it is good until first batch of bad gas you pump in. :lol:

Wow, thanks for the great info guys! I had an 02 which had the external filter, so I just assumed this one did too.

 

Thanks again!

Has anybody added a pre-2003 truck style in line filter? It should not be that hard to do.

I have to say I agree with you guys. This does not sound too smart considering how often I had to change the fuel filter in my '02.

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      2020 Trailboss 6.2 replacement

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
