thanks!

Somewhere here (search) I believe someone measured the various tanks.

Unfortunately they did. That is what I am stuck with in my 89 GMC suburban. Is it possible to upgrade to the 40 gallon tank in my 'Burban?imiceman44 said:I didn't know they offered the 31 gal tank in the sub.
I have the 40 gal, and it won't fit.
The 45 gallon from my van won't fit in either the sub or the blazer, it's wider than the frame in those trucks.![]()

sorry to bump an old thread, but looking to see if a 31 gallon tank (2" taller) will fit in a K5 without mods
