Gas tank swap?

[mhaywoodcz]

Hey Guys, I have a question regarding gas tanks, searched but didn't really find what I was looking for. I have a 2002 Yukon Denali 6.0 152k miles that is mainly used for pulling a boat or camper. It does great pulling either, but all in all I have to stop alot for gas. (yeah, first world problems etc)
Typically I get around 12 mpg combine empty and so far with the boat around 10mpg. Have a 10 hour camper pulling trip coming in the spring. Just seeing if a suburban or Yukon XL gas tank will fit the regular yukon.

I don't know if it is there in the 2002 ECU, but later truck ECUs have the provision for a saddle tank like the 2500 Suburbans have. Now, I believe that to be an 11 gallon tank, but some folks will insist it is a 6 gallon tank. Regardless, you can run a tank back there -- assuming you have the provisions -- and would give you 40 to 100 miles extra range (the tank keeps a reserve of a gallon or so). Anyway, it is a consideration. Good luck! The 6.0 is great at passing everything except gas stations... I know because I have 3 of them.

What's an ECU?

That's the computer that controls the main functions of your Yukon. Maybe it's ECM? Sorry if I got that wrong.

Came to say the same thing. I think I learned from this website that the suburban 2500s Had the option for that 2nd tank but you have to ditch the spare tire if I’m not mistaken. There’s a thread somewhere


This thread talks about it

Fuel tank in place where the spare tire is located.

Has anyone replaced the factory fuel tank that is next to the driver side frame rail with a similar sized one in place of where the spare tire is located? I've been toying with the idea of long traveling the rearend but the factory gas tank is in the way for the to triangulate the upper arm to...

You do not have to ditch the spare tire -- on the Suburban/Yukon XL 2500s. The spare tire is actually hung from the tank.

Thanks for the info and old thread to reference, since I want to keep my spare, I will just keep stopping every 200 miles. I guess its goes along with my New Years goal to "slow down and enjoy the little things"

As you get older you'll thank yourself for the more frequent comfort stops. P time.
