Magnetic Fuel System Cap for GM 3.0L Duramax (2020–2026) | Fits Silverado & Sierra, Prevents Dirt & Contamination

Great little cap to keep debris from potentially entering your fuel system. Fits just tight enough feel solid. Typical printed material that should hold up since it really just a press in cap. No threads to strip or break. Plus, it appears to be made in Michigan, my home state! Some say the magnet is too weak, well it's just there to hold the cap when you are fueling. seems strong enough for the intended job. Better than tossing the cap onto your bed rail! The printed "Diesel Fuel Only" is a nice touch top remind my wife the truck take diesel unlike her Blazer.

Perfect fit. Great quality. Great price & looks good. The magnet holds the cap very well.

Perfect fit every truck should have this cap installed coming from the factory

Its not a fancy metal fuel cap but its my 2025 Chevy Tahoe Z71 with LZO 3.0 Duramax diesel fuel fill tube perfectly. Easy to put on and easy to remove. Overall a goo value. I would have to assume it would fit any 2022-2025 Tahoe/Yulkon/SUBURBAN DIESEL application. It’s just snug enough not to be loose and provide a good seal but easy enough to pull on and off without much effort (unlike some expensive alternatives). A very small magnet with sticky tape backing is provided that you can stick to the inside of your fuel door (if plastic) that you attach this cap to when removed for fueling. Some people have stated that the magnet is weak and I agree but it holds the fuel cap while I fill up and thats all its supposed to do. If I drive off and hit a bump, Im sure it will fall off the magnet but shame on me for forgetting to replace the cap and close the door when Im finished.

Works as intended and looks good.

Great way to keep dirt, water and other debris out of your tank. Fits perfectly to allow air to still enter. Highly recommend to prevent someone from accidentally putting DEF in your fuel tank. Unfortunately, I had somebody do that.

Perfect, I no longer have to worry about water getting into the tank

Perfect fit and MADE IN THE USA!!
