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.
