Review: Worked great so far. - First time I have used a thread sealant on a fuel system, I used this when replacing a defective shut off valve on a generator and it worked great.

See technical specs here: https://www.fedprobrands.com/products/pipe-thread-sealants/gasoila-e-seal-thread-sealant.html **Q: Is this appropriate for fittings on a dispensing pump for diesel fuel?** A: It’s about the best I’ve found for any diesel or gasoline engine application. **Q: Will this work on gas tank drain plug that is leaking slightly??** A: Depends on why the plug is leaking. If the plug is threaded and the threads are damaged, probably not. If by "slightly" you mean weeping and if the threads are ok, then it may be sufficient. The reason that I used Gasoila E-seal was because of its resistance to degradation by Ethanol, especially in high percentage Ethanol/Gasoline blends. The product is a sealer, not a glue or filler. **Q: Has anyone used this on fittings that are exposed to engine oil?** A: It is rated for use with ethanol gasoline. Ethanol is much more harsh than engine oil. I would just avoid getting it inside an engine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great so far. *by L***E on August 18, 2026* First time I have used a thread sealant on a fuel system, I used this when replacing a defective shut off valve on a generator and it worked great.
