2019-2026 Silverado / Sierra 1500 2500 3500 & LCF FPCM 13565641 — Programmed to Your VIN

GM Fuel Pump Control Module (FPCM) — also called a Fuel Pump Driver Module or Fuel System Control Module (FSCM) — part number 13565641, programmed to your VIN and ready to install.

Used across 2019-2026 Chevrolet Silverado and GMC Sierra gas trucks (1500 through 3500), including the 2500 HD / 3500 HD with the 6.6L L8T V8, and Chevrolet LCF (Low Cab Forward) commercial trucks.

How it works: this module acts as a smart driver, using Pulse Width Modulation (PWM) to vary the voltage sent to the in-tank fuel pump. That lets the ECM request dynamic fuel pressure based on engine load, rather than running the pump at a static 100% duty cycle.
