If you clean the crack and degrease it and rough up the area I don't see why it should not work. I assume the tank is metal and not plastic . **Q: will this fix a leak on a plastic lawnmower tank ? cheers.** A: Hi thereI used J B weld on a metal diesel tank after cleaning area of all traces of fuel and warmed the tank with a hair dryer before applying the putty. All worked well. You might want to roughen the plastic around repair area with a coarse file to get a good bond as smooth plastic might prove tricky. All the best. **Q: Will this work on diesel fuel pipes on a car ?** A: I don't know the answer but with diesel being a fine oil it creates a film on the surface of metals and plastics making it difficult to get repair substances to adhere. Hope that this helps. **Q: Have a air conditioning core with pin hole leak, might this work on copper pipe?** A: I have used this successfully on steel that is subject to vibration and heat changes, if the copper core is subject to heat then I don't see a problem but am not sure how it will react to lower temperature such as experienced on the cooling side of air conditioning . ## Customer Reviews ### ⭐⭐⭐⭐⭐ An excellent fast setting product that seals small petrol leaks. *by M***N on 12 July 2026* An excellent product that has sealed a slight petrol leak.

It sets quickly in hogh temperatures. ### ⭐⭐⭐⭐⭐ Does what it says on the tin *by D***N on 13 October 2026* Does what it says on the tin ### ⭐⭐⭐⭐⭐ A good product for patching up small leakages. *by G***L on 1 September 2026* Very good product, just a little bit difficult to get it stick at first and it requires a bit of effort. Very important to use a proper degreaser (break cleaner) and keep pressure at least for a few minutes, ideally till it sets, to avoid leakages lates - if proper degreaser is not used, diesel/fuel will push through as the putty won't stick properly. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/271180370-j-b-weld-plastic-metal-oil-diesel-petrol-tank-repair](https://www.desertcart.tn/products/271180370-j-b-weld-plastic-metal-oil-diesel-petrol-tank-repair) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-27*
