Wehrli Block off Plate for GM 6.6L Duramax

If you're upgrading the fuel system on your 6.6L Duramax and planning to remove the factory CP3 from the engine valley, there’s one small but essential piece you don’t want to overlook—the block-off plate. The Wehrli 100024 Valley CP3 Block Off Plate is designed to cleanly and securely seal off the original CP3 location once it's been removed, whether you're running a dual fueler setup or a full CP3 delete. It's a simple component, but it plays a key role in maintaining reliability and a clean engine bay. This plate is machined from high-quality billet aluminum, giving it the strength and precision fit you’d expect from a Wehrli product. It features a durable black anodized finish that resists corrosion and looks right at home in a well-built engine bay. An engraved Wehrli logo adds a nice finishing touch without being over the top. It also includes a high-quality O-ring to ensure a leak-free seal, so once it’s installed, you won’t have to give it a second thought.
