Description
The XDP Water In Fuel (WIF) Sensor Delete Plug XD137 is a quick and simple solution to ending all the issues caused by the factory Water In Fuel (WIF) Sensor in your 2001-2016 GM 6.6L Duramax. The factory sensor is made of plastic and often times just doesn't last. Over time the sensor can strip, crack, and even cause air leaks in your fuel system. On top of that, many Duramax owners question the accuracy and effectiveness of the factory WIF sensor.
This billet aluminum Delete Plug simply threads into the bottom of your filter and eliminates the existing sensor. All you need to do is disconnect the old sensor and remove it. Removal will not cause any warning lights. Includes new o-ring. The XDP WIF Sensor Delete Plug has also been designed to work with a 3/8" ratchet for easy removal and installation.
Features:
- T6 Billet Aluminum Construction
- 3/8" Ratchet Drive For Quick & Easy Replacement
- Works With XDP WIF Wrench & Other Aftermarket WIF Wrenches

Worked like a charm on my 2015 LML. Stopped my fuel leak after buying the cheap autozone replacement WIF sensor.

Used this with a fuel filter bypass. No more cheap plastic parts, all aluminum.
Torledsky (FL) | February 9th, 2023
This plug resolved so many problems. I wish I found this years ago. The stock plastic plug backed out and after buying two in the last three years it’s worth the buy!

Simply disconnecting your WIF sensor will not trigger a check engine light. (You can test this by disconnecting your current sensor wires and you’ll see that no check engine lights are triggered.)
