Lawnmower petrol tank (plastic) has a very small leak between the joints, what can I use to seal the tank. Thanks
Hi @Richard44,
Unfortunately, due to the types of plastics typically used in petrol fuel tanks, I’m not aware of a filler or adhesive that will reliably bond and hold long-term. Fuel can prevent many sealants from curing properly and can also break down repairs over time, so even if something appears to work initially, it often fails again.
My recommendation would be to see if the fuel tank is still available as a spare part and have it replaced. Most lawn mower repairers should be able to source and install the correct tank for you.
If you happen to know the model number of your mower and it was purchased through us, I’d be more than happy to help look into whether the manufacturer still supplies the tank as a spare part. You can also organise this through your local store’s Special Orders desk. The team there can take your details and arrange for our Spare Parts team to contact the supplier on your behalf. There is also an online spare parts enquiry form available if that’s more convenient.
Please let me know if you have any questions.

I tried a variety of hardware silicones for a small 2-stroke plastic petrol tank.
Totally failed.
