Replace Plastic Gas Tank on Tiller

So, long story short, a neighbor is loaning me her tiller that she loaned to another neighbor. When she got it back from the other neighbor "something had fallen on top of the tiller and cracked the gas tank". The gas tank is destroyed - several hairline cracks and it leaks gas all over the place. The gas cap is broken, too.

I want to use this tiller tomorrow morning.

If I find another small engine gas tank, can I just replace the broken tank with the new tank? I'm sure it won't be a match but if I can find a way to attach it securely, the fuel lines are the same size, and it doesn't leak - would it still be safe to do?

The tiller is a Craftsman with a 5.5 HP Briggs and Stratton.

Thanks for your advice and suggestions!

 

Yeah you can do that, but be carefull. Make shure the tank is secured so it wont fall off or slip and leak and cause a fire. There's probably quite a few of mix and match setups out there that were just going to be temporiary and became permanent.

Yeah, it will work, but be sure as mentioned above that everything is secure. And I sure hope the previous "borrowee" has ordered the correct replacement tank?
