    What are we talking about here? What is the tank on and what is it made out of?

    If it was my machine? NEW TANK
    For metal they make some stuff called PETROSEAL,don't know that i would trust anything for a permanent seal other than rewelding it and that may not be advisable. For obvious reasons.
    Just my .02

    I am selling a BadBoy CZT 42" for 5K! it has 16 hours and has a powerchute 2 bin bagger. It was to big a mower for yard and I downsized! Mower is worth a look, you are far away, but maybe worth a drive?

    A plastic gas tank is likely polypropylene. That is a thermoplastic which is weldable.
    It requires some skill however, and some plastic welding equipment.
    If it is polypropylene, there is no magic adhesive you can use on it. I've glued polypropylene with hot melt glue (it actually holds quite well, IF the base plastic is heated to pretty hot with a heat gun), but that bond will dissolve in the presence of gasoline.
    A welded tank can be as strong as new, if done right.

    The important thing to note, is to be safe, and get all of the gas AND FUMES out. That can be the most difficult part.

    I later learned of "Seal All" and "Shoo Goo"?? at the auto parts store. I just didnt feel comfortable not being able to see the tank with ease. Knowing it's a new tank puts me at ease...I've already put a good chunk of change in her, so $71 more isnt gonna kill me...I do appreciate ya'll tho... be safe...Gunner
