Compatible replacement fuel tank

Hello, I'm working on a husqvarna Yth2148c riding mower and the plastic fuel tank has some cracks in it. Is there a plastic tank repair that will withstand gas with or without ethanol? Or is there a suitable tank that can be swapped in place of the oe one as that tank has been discontinued.

I would be open to a good used one if someone happens to have one and doesn't want an arm and a leg for it.
Trying to repair this for a neighbor so keeping cost low is kinda a good thing.

Thanks for any assistance you all can give.

Thanks, that would be great, I've talked to jb weld and they say their fuel tank repair won't hold up to gas fumes. Such a pain, their was nothing wrong with the tank but his ranch hand took it all apart because he said it wasn't getting enough fuel.

It just needed another fuel pump as the two aftermarket ones I ordered both failed. So he strapped it on the hood and it's fallen and been kicked around.

Now it's a pain to find one and am gonna have a worthless machine if my neighbor dosent want to spring for a used tank if I can find one.

So which products did you use from them? Is you paint it on the outside or dump it inside the tank?

Ok, it's holding fuel just fine..
 
Again, mine was a pin hole and a horizontal seam that was leaking (not much of a leak)..
 
For as big as your tank is, some suggestions:
   -  Scruff the area cracked, orbital sander or such to rough up the plastic
   - Use JB Weld HIGH TENSILE strength on the EXTERIOR ONLY:
    ( https://www.homedepot.com/p/J-B-Weld-Two-1-oz-Twin-Tube-Cold-Weld-Epoxy-8265-s/100189012 ) 
 
 -Using some cut down and straightened paper clips (3/4-1" in length) IN the JB weld before it sets
       will make it MUCH STRONGER.. It'll look like stitches (maybe an inch apart from each other)
 
  - Once that sets up, then I'd use the tank sealer..
 
Just to note, that sealer did seep out thru the pin hole (just a little). The horizontal seam, nothing oozed out but IS sealed up..    The JB Weld will strengthen the crack (but not touch the fuel), the sealer should keep fuel away from the JB Weld..
 
Please post back how it goes...

The machine is a very old sod cutter with an updraft carberator (B&S about a 10 HP).  
 
Its's a customers (Tree guy) and his machines get abused by his crew..
It's going to see regular ethanol fuel.

 
I did a repair on a plastic RV holding tank (actually, part of it was gone when 
a tire blew and took it out) with fiberglass.
 
What I think would work for you is fiberglass.  Again scuff up the plastic real good
and layer the glass over the entire damaged area.  Getting a good bond to the plastic is the key.
Several layers should be plenty.  
 
They make fiberglass tanks for boats and other machines so it is do-able.. 
 
Hope this helps...
