I have a BS Quatro plastic fuel tank and houseing(the kind that covers the entire motor) that is leaking at the seam, I have tried epoxy for fuel tanks, won't tick to the plastic, I have tried Seal-All for oil and gas, won't stick to the plastic. A mechanic says to solder the seam with a pencil type solder iron and use small strips cut from the plastic cap of a spray paint/carb cleaner can for solder. Does anyone have any experience repairing plastic fuel tanks? I thought I would ask before I start melting the seam. Oh, and yes I going to drain the remaining fuel and rinse and dry and test the vapor with a torch to make sure it is empty. Any help would be appreciated. Thanks and have a nice day. Geo
I have successfully welded plastic exactly as your mechanic describes but it was to hold water. Be careful with the fuel fumes.
I have done it too, but don't really reccomend it. You should be able to pick up a tank used from a small engine shop pretty cheap. Safety is a concern with that type repair.
I have the same thing $27.00 from Snapper
for a new tank.
What is the model, type and code numbers of your engine? There is a standing recall of certain Briggs fuel tanks which were produced in the early 90's that Briggs will replace for free at any authorized dealer. Post back with your numbers and I'll check if you have the affected tank.

Thanks a bunch for checking this out. Have a nice day. Geo
ounce it`s welded it will just start leaking further down the seam.
I suggest you just replace the tank.

IF YOU HAVE A 122702 ENGINE IT IS A QUANTUM SERIES (NOT A QUATRO) I HAVA ONE I WOULD BE GLAD TO LET YOU HAVE IT HOWEVER YOU WOULD HAVE TO PAY SHIPPING FOR THE TANK,I DONT KNOW YOUR WHERE ABOUTS BUT IF THE SHIPPING FROM ZIP CODE 21227 ISNT TO MUCH FEEL FREE TO EMAIL ME AT (email addresses not allowed, moderator) ..... HOWEVER IF THE SHIPPING EXCEEDS $12.00 YOU PROBABLY CAN FIND A USED ONE CLOSER TO YOU.IF YOU HAVE A LOCAL RECYCLING YARD(DUMP)THAT IS A GOOD PLACE TO LOOK.

Thanks for the great info. I have the same problem with a leaking plastic fuel tank. My model # is also 122702 (type 313901) and was built in 1991. I called Briggs and Stratton Customer Service and they were very helpful. They will be sending me a new tank free of charge.

Hi puey61, I would appreciate if you could check on my model Briggs engine. The tank is leaking pretty bad. It's model 121602 type 0121-E1. I think it is newer that early '90s, but not sure.
Thanks.

I've got a Yamaha YZ125 with a leaking gas tank (cracked at multiple seams). Replacement gas tanks for this motorcycle are hard to find an ridiculously expensive -- I'm not going to pay $250+ for what amounts to a 3 gallon plastic bottle with screw holes . The whole bike only cost me $900. I have already failed to bond the tank with two different epoxies that were supposed to be gas/solvent resistant. One held for a week before it turned to jelly and oozed out with my gas, the other withstood the gas, but wouldn't stick to the plastic for any length of time...it just peeled off like skin. Has anyone else out there had any luck with this powerpoxy? \
UPDATE: I just saw this video on use ******** to structurally bond polyethylene and it looks like it might do the trick. Anyone else tried it?
I just noticed that someone named Shadeladie edited my post and removed the name of the product I mentioned for bonding polyethlene gas tanks, so I'm reposting it. I have no idea why she/he felt it necessarry to remove the info. The stuff is called TAP Poly-Weld, and can be found at TAP Poly-Weld Adhesive: TAP Plastics and there's also a nice video on Youtube showing heat treat and bond polyethylene. It involves using a propane torch to treat the plastic first, so if you plan to use it on a gas tank, you'd better be darned sure it's 100% clean and free of fuel vapors. In the end, I just ended up coughing up the cash to buy a new gas tank because I was tired of trying new products, so I still don't know if this product will work to repair a polyethylene gas tank on a YZ125. Maybe someday someone will post the answer here, but probably not if the admins keep editing people's posts to remove all the useful info.
