Fuel Pressure Sensor Fooler & Sensor Delete Plug Kit (2011-2016 6.6L Duramax LML)

The Fuel Pressure Sensor Fooler Duramax LML kit solves two of the most common issues found on 2011–2016 6.6L trucks — failed or leaking fuel restriction sensors. Designed and built in North America, this plug-and-play kit restores reliable operation without messy wiring or costly replacements.

The factory sensor that monitors vacuum between the fuel filter and CP4 pump often fails in two ways: electrical failure and sensor leaks. Both can trigger false “Change Filter” warnings, zero filter life, or even crank/no-start problems.

Dieselr’s Fuel Pressure Sensor Fooler & Delete Plug Kit eliminates these frustrations. The fooler connects directly to the OEM harness, sending the correct signal to the ECM so fuel restriction data remains accurate. The delete plug replaces the original sensor completely, sealing the port with a precision o-ring for a leak-free finish.

Why Choose Dieselr’s LML Sensor Fooler Kit

• Corrects false “Change Filter” alerts
• Stops leaks caused by aging sensors
• O-ringed delete plug for clean, reliable sealing
• Compatible with stock or lift-pump systems

This kit won’t hide real rail pressure problems, but for failed or leaking sensors, it’s the exact fix you need. Reliable, durable, and simple — the Fuel Pressure Sensor Fooler Duramax LML keeps your truck on the road and out of limp mode.
