WIF Plug for Duramax-with drain valve

Replaces the OE WIF sensor with a simple, pretty much indestructible plug made of anodized aluminum. Accepts KD WIF wrench plus has a 3/4″-19mm hex to unscrew. Drilled and tapped with 1/8″ NPT to accept a drain valve. Drain valve included.

“The OE filter basically never collects any appreciable water so the sensor is pretty much useless. Over time the sensor can leak so why not just chuck it? Removal will not set check engine or water in fuel warning light.”- JK
