Anyone switch out their 26 gallon fuel tank to the 37 gallon one in the Yukon 2500

Oh and here is the tasty new 4l80e and denali on the lift hehe....

I would say the 37 gallon tank is longer. In the 90s trucks that's how it was.
I think it won't fit but I am hoping it will. It may hit the back axle

Alot of $

Yes alot of $$$$. Plan your budget then add in another 40% on top of it

Oh the dealer said no go on the fuel swap....but I don't necessarily believe it. Going to look for another option

Dont forget that going to the larger tank adds more gasoline weight which REDUCES your max towing weight.
