Well, my lawn is just coming out of winter and the grass is as matted as a 12 year old boy's head that hasn't been combed for 3 days.  I filled up the tank on my Broyhill M4100 last weekend--planning to run a de-thatcher through it, and quickly discovered another problem with the machine--fuel was coming off the front of the plastic tank in great abundance... not pouring, but a pretty steady drip. 

 

I got siphoned about 2 gallons out of the tank and the dripping stopped.  Then, while driving it I stopped suddenly and a slosh of fuel came up over the top of the tank.... methinks I have a crack or split in the tank. 

 

I don't know what a new tank would cost for this little gem, but I'm sure it's pricey.  Is there any way to mend a plastic tank, or do I need to bite the bullet and buy a new one?

Smitty, Check out this thread on ABS and Plastic repair. I just fixed a ga tank on my push mower this way also.

When i worked at the autobody shop years ago they had plastic welder tool (forgot the exact name) looked like a big soldering gun that was used to fix small cracks in bumpers. I think they used it on a saturn once too.

Thanks... now that you mention it, I remember seeing that thread once before.  Good Info.

 

I also bought a HF hot air plastic welder years ago, and promptly abandoned it as it didn't work well at all--no temperature control to help keep the plastic in just the right state, etc. 

 

I may try to do it with a soldering iron, though I'll disconnect it before trying to weld... don't want any sudden "disassembly": to occur.

I've had excellent results with this product It stays flexible when dry, seems to seal or glue nearly everything.

The last tank I repaired had a slit in it that was approx 4 inches long.

You just have to be careful with the iron or you will melt thru. It will cool off too quickly if you in plug it.

Practice on something else to get used to it.

Well, I found out that the tank wasn't just cracked... it looks like it had been crushed on one corner.  It's a 4 gallon tank, but even with only about 1.5 gals, the fuel come sloshing out of the crack and onto the center console of the machine when I stop.

 

A short call to Broyhill and I got a new tank for $135 delivered... not the greatest price for a plastic fuel tank, but pretty good for a proprietary tank.

Smitty, sorry to hear you couldn't save it. I have taken another tank and used ti for patches for others. Price doesn't sound to bad for that big of a tank.
