My 7025 Lawnboy gas tank is cracked and I'm wondering about maybe trying to find good replacement, with the 3 correct tab screws. I have an idea about what one might cost, but I was wondering about the best price, and a trustworthy seller? Thanks

Hi and welcome! Cracked as in leaking or cracked as in broken mounting tabs? Also here is a link to what appears to be a decent used one. Bill

Cracked on the top backside slope of the tank and leaking. I did see that on ebay, a few days ago but it doesn't have the "Lawn-Boy" plastic molded on the front like mine and it does not include the 3 screws, which I need because mine are not the correct screws. That tank on ebay is just ok, not what I'm looking for.

Okay. The tanks for the 19 inch and 21 inch are the same. The replacement tanks and the later production Lawnboy models did not have the logo. That way they could be used on either the Lawnboy or JC Penney models. Neither mine or my neighbors had the logo but not sure if they were the original tanks. The screws are still available from Lawnboy. 609808 for the top 2 and 607526 which has been subbed to 32105-12. As I recall on mine I used the regular truss head screws for the top, like the ones on the D-600 series and early F series and I used a Phillips head bolt with a locking nut and flat washers for the front. I have seen new tanks come up on eBay in the past but they are rare as most of the old ones had broken mounting tabs. I also tried a Lawnboy decal on mine to mimic the raised Lawnboy letters on the older ones but the outgassing of the fuel from the tank made it bubble up. I would grab that eBay one while you can. That style tank was only around a couple of years so they are not plentiful. Good luck. Bill

Well I would assume with a crack in the tank it leaks and is not usable. If that is the case get a used one that works so you can use the mower and keep a watch out for a better one. I had received a 1978 model 5269G from a friend and the shroud/tank was all scratched up. About 6 months later a NOS shroud came up on eBay and I snagged it. Keep a watch out. You never know. Bill

I have plastic welded a shroud from a Toro snowthrower. You need a very clean soldering gun tip for best results. Make sure fuel tank has been drained and washed thoroughly. Leave cap open. Perhaps fill with water before and while attempting. Bill

Yes. Also if there is anywhere on the bottom of that tank, such as an edge or rib, to shave off some green plastic you can use that for filler. Bill

I assume I just use heat from the gun and try and fuse the plastic together?
Yes, you can use any soldering iron, although there are purpose-built ones like this:

I would not recommend this. It will chill the plastic and will also get into the cracks and prevent bonding. The plastic should be clean and dry.

I fixed my ancient Ryobi tank. If you need some ‘filler’ find an old plastic jug labeled HDPE. Takes a bit of melting ang gushing around, but it seems to work. Laundry detergent jugs seem to fit the bill
