Review: Tractor Diesel Connections Fixed - Update - gasoline line! - I was having constant leaks from the shut-off fuel valve on my farm tractor tank. The copper crush washers and banjo bolts were not working and replacement parts were on order. But due to shipping delays it will be weeks for parts, so I ordered this stuff. Once the area was clean and dry, I brushed it on each side of the crush washers and was careful to limit the amount near the banjo bolt openings. I didn't wait a few minutes as written on the can, but installed the parts quickly back on the tank. Once in place and tightened, I waited about 20 minutes and refueled, there were no leaks. Its been several days of heavy work and still not a drop has gotten past this stuff. I will probably wait on replacing the parts even once they arrive since this stuff is working so well. Also works on some fuel high-pressure lines. I may try it on some steering lines on some other equipment. I would suggest that cleaning the areas to receive this stuff is probably the key. Hit your areas with a can of carb/choke or similar. Then once it is all dry, go to work with the goo. If you try and add it to diesel covered parts, it looks oily, sorta like it is forcing the diesel into droplet or scattered patches on the parts, which would then allow a leak. So you want a good solid coverage. Update: March 20, 2024. I have a Husqv riding mower that I was getting ready to use for spring cut. Took the carb off to clean it all up and the o-ring/gasket in the float bowl broke. Of course all it kept doing was leaking on me. No replacement on hand and needed asap. So I went to my trusty Aviation gasket goo. Cleaned carb bowl up real good, put goo on both areas and sandwiched old gasket in between (see pics). The brown goo squeezed out around the lid, but I knew from diesel tractor that it could handle fuel. So I hooked fuel lines back up and away I went. Just so you know, diesel tractor is still sealed with goo and working perfect from back in May 2022. I try and leave quality reviews to help people solve the same issues I have. This stuff is dark brown goo, that is sticky/tacky from the get-go. I might not use it to seal a fuel issue on my Learjet XJ19 before taking off, but I might use it in mid-flight while I'm holding on to the wing repairing the jet fuel lines : ) No I don't have a jet. But if I did, that would be really cool movie stunt.

The first one I bought from a local auto parts. When the first one ran out it was over 20 years old and still good. It will last a long time as long as you seal the lid well and don't leave it open for long periods. I use it then put the lid right back on **Q: Is this compatible with plastic fittings? I have a diesel storage tank with 3/4" threads that leak a little and I am looking for a sealant.** A: I primarily use this on Triumph motorcycle cases and it is the best Permatex (or any) product for the job. I've also used it on rubber pipes to metal banjos and it worked well there too. I suspect that it would work well in your situation but I have not used it on plastic and there are so many kinds of plastic that I would test it first. Personally, on threads where gas or oil is involved, I use the yellow Teflon tape -- it seals gasoline so diesel should be no problem. **Q: My red plastic Moeller marine portable 6 gallon fuel tank has some small gas leaks around the screw on caps - think it would be safe to use...?** A: It would probably be safe to use but when mine was apparently shipped in a non-pressurized airplane hold. The cap was intact but the sealer had leaked out all over. I will buy locally next time. Auto stores may have it or may be able to get it. **Q: would this work for marine freshwater outboard motor such as water pump gasket sealer** A: I don't see why it won't..I used it on my oil pump ad my water pump...works great...no leaks..oil, antifreeze does not have any affect on it..Good stuff. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Tractor Diesel Connections Fixed - Update - gasoline line! *by S***H on 22 August 2022* I was having constant leaks from the shut-off fuel valve on my farm tractor tank.
