Customer Reviews (4.8 / 5 · 5 reviews)

David ★★★★★

The Viton O-ring on this plug feels way more durable than the stock rubber one—should hold up better against fuel over time. It seated perfectly in the rail on my '08 Duramax with no leaks. Exactly what the old pressure relief valve needed.

Lucy ★★★★★

Swapped this in during a fuel system service on my 2004.5 Duramax and the fit was spot-on for the rail relief plug. The Viton O-ring held up without any weeping, and it’s nice knowing the pressure relief valve is replaced with something solid.

Aurora ★★★★★

The Viton O-ring on this plug feels much more durable than the factory rubber one, and it sealed perfectly on my 2008 Duramax. Installation took maybe ten minutes, and the fuel rail pressure is holding steady now.
