2020–2026 GM 3.0L Duramax Diesel Fuel Cap

Very high quality, perfect fit!

Pretty sweet

I love that PPE made this and priced it reasonably. Once its on, nice fit btw, it looks like it was meant to be there. Keeps the dirt and dust out of the gas entry tube and just looks cool even though no one sees it! And one more benefit…Maybe it will also slow down someone from putting def into the gas tank.

Solid Cap

Got this for my 2026 Sierra 3.0 liter. Fit is secure. This is a solid piece of aluminum. It feels hefty and durable. Satisfied with purchase.
