Anyone have a maintenance schedule for the 2007? I couldn't find anything on it in the manual. On my 97 Tahoe, I always liked to change it a bit early. I now have 24k miles on my 2007; I'm wondering if it is the same schedule (every 30,000) I found it odd there was no mention at all in the manual. Thanks.

The 2007 Tahoe does not have a user serviceable fuel filter; it utilizes an in-tank strainer/filter that requires no periodic servicing.

Thanks Z. Long time lurker of this forum and thanks to you, I inform my dealer of problems before they even know about it.

E85 related, I presume?

Thank you for the compliment.
Actually not E85 related although that is an excellent deduction, the reason is that there are two conditions that can cause premature fuel pump failure; one is low fuel level, the pump is cooled by fuel and low levels also cause the pump to cavitate as fuel sloshes in the tank, only the owner has control of this as it’s not good business to make the last 5 gallons of fuel in the tank unusable.


The other thing that can cause a pump to die is a plugged filter element that goes unchanged; the new in tank system is engineered so that it will not clog under normal usage.

Changing the fuel filter on our (now sold ) 2005 Mazda Tribute took all of 15 min, including going to the store.

On the 2007+ Tahoe, you have to actually drop the fuel tank! With 135,000 on mine, I'd like to replace it, but I'm not dropping the tank if 'nothing' is actually wrong.
The sad thing is on the mazda, the fuel filter was FILTHY. When I took it off, the blackest dirtiest fuel came out of the thing, with 150,000 miles on it.

Wonder what the Tahoe one looks like in it's 'not serviceable' position

check youtube for a how to video, I found one for my 09, they should be the same. Too much work for me, since I don't actually have an issue...

for smaller cars the numbers work out as such:
The old system may pump 30 gallons in an hour and returns 28 gallons to the tank while the returnless system pumps 2 galllons and return zero. the service interval for the filter can now be 5x higher

in any case, it's had, at least, 8,437.5 gallons run through it, to date.
