    The suburban tank will not fit in a blazer.
    It will fit in a long bed truck in place of the spare tire.
    :D

    I thought the small suburban tank (31 gallons) was the same as a Blazer 31 gallon tank, and the 40 gallon Sub unit wouldn't fit?

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

    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. :o

    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?

    I would think it would be just swapping tanks & straps on the Burb.

    I read the difference between the 25 and 31 in the Blazer is only 2":eek1:

    28 x 28 x 10.5 and 28 x 28 x 12.5.

    Yeah, you can even get the 44gal from a diesel sub, that is the biggest you can fit in the sub.

    OOOooooohhhhhh. 44 gallons... Now that sounds like a good time. Would I need to upgrade my sender when I upgrade to either tank from my 35 gallon tank? Or will my stock sender unit accurately show my fuel level?

    I only know they are different between gas & diesel. Don't know if your 35 will register correctly in a 44.

    Could be fun though!

    "Hey! Buggy, the needle's on EMPTY!"

    "Screw it! I'm driving the 100 miles to town!"

    Or:

    To friends

    "Geeze guys, I'd drive but the tank is on "E" !"

    :haha::haha:

    I can't answer if it will work or not, but depth is the only critical thing when talking similar sending units. All operate/measure the same way, if the depth of the tank is the same, the senders will interchange. (with the normal exceptions like TBI, emissions, etc)
