    My fuel tanks baffle is broken and unattached. So I was looking for a new replacement. In JC whitney I found 22gauge steel replacment 31gallon for $140. 22gauge sounds thin to me. polyethelene 31 gallon for $200 (I think I found the company that makes them, MTS, but there site didn't list prices). and a 16gauge 43gal tank that sells for $469 in JC whitney but I think is the same tank as Northwest Metal Products tank that sells for $410 on there site. Does anyone know of any other fuel tank vendors on the net? I've been searching google for a while. Has anyone used any of these products? thanks in advance.

    I haven't used them myself, but a friend replaced the tank in his 87K5, and I saw it before he put it in. Seemed pretty strong to me. And he got it from JC Whittney. I thought it was ok, and have been considering ordering a 31 gallon to replace my 25. Hope this helps.

    Make sure you get (and they list) an '87-91 tank, since you won't get baffles if its pre-'87.

    I don't *think* you could fit a 41 gallon tank in there.

    If you used one with "narrower" seams, you might be able to get more gas in there, but I don't believe with a 31 gallon tank there is any more than 1/2" clearance between the tank bottom and plate, and probably less than 1" front/rear clearance as well. Pretty close to the framerails as well, but again, I think a lot of that is the seams that stick out a bit.

    It would have to go inside the framerails, I can't imagine getting a 41 gallon tank to fit safely anywhere else. All I was saying is that to get that large of a tank in, you have to change the dimensions, and with a stock skidplate, length or depth isn't something you can change. Width maybe, but more likely, it has to be deeper.

    You can get the 41 gallon tank in there, but the stock skid plate just isn't going to fit over it. /forums/images/graemlins/frown.gif That size tank may also interfere with the trailer hitch. /forums/images/graemlins/shocked.gif I put a 45 gallon aftermarket tank into a '72 Blazer once. That tank used EVERY square inch of space available under the rig!
