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.
