E4042M Electric Fuel Pump Module Assembly For Chevy Silverado 2500 HD 2011-2016; For GMC Sierra 2500 HD 2011-2016

E4042M Fuel Pump Module for 2011–2016 Chevrolet Silverado and GMC Sierra HD Trucks

Extended cranking, intermittent no-start, low or unstable fuel pressure, hesitation under load, stalling, abnormal pump operation, or an inaccurate fuel-gauge reading can involve the in-tank module. This BDFHYK E4042M electric fuel pump module assembly is an aftermarket replacement for specific 2011–2016 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD trucks with the 6.0L gasoline V8. Confirm the bed length, cab-and-chassis exclusion, tank design, connector, sender layout, and OE number before installation.

Confirm E4042M Silverado and Sierra HD Fitment

• 2011–2016 Chevrolet Silverado 2500 HD with the 6.0L gasoline V8 and matching approximately 6.5-foot bed configuration
• 2011–2016 Chevrolet Silverado 3500 HD with the 6.0L gasoline V8 and matching approximately 6.5-foot bed configuration
• 2011–2016 GMC Sierra 2500 HD with the 6.0L gasoline V8 and matching approximately 6.5-foot bed configuration
• 2011–2016 GMC Sierra 3500 HD with the 6.0L gasoline V8 and matching approximately 6.5-foot bed configuration

Important Truck Configuration Restrictions

The verified E4042M applications are not for diesel engines and exclude Cab & Chassis configurations in the referenced fitment data. The bed is commonly listed as 6 feet 6.8 inches or approximately 6.5 feet. Confirm cab style, bed length, wheelbase, tank capacity, tank position, VIN, and RPO information.

E4042M OE and Interchange Number Check

Listed references include E4042M, FG1746, EFG1746, P77016M, SP4088M, SP6741M, A49000, M100105, M100120, MU1960, MU2189, 13577632, 13581920, 13585445, 13585450, 13589707, and 19301692.

Compare the flange, connector, fuel-line fittings, module height, reservoir, pickup, strainer, sender, float arm, seal, and lock-ring engagement with the removed assembly. A 6.0L engine alone does not confirm tank fitment.

Check the HD Truck Fuel System Before Replacing E4042M

• Measure fuel pressure during key-on, cranking, idle, and load
• Check available voltage and ground at the module under pump load
• Inspect the relay, fuse, wiring, connector, filter, lines, pressure-control components, and injectors
• Test the sender and gauge circuit separately when the fuel-level reading is inaccurate

Clean rust, sediment, water, degraded fuel, and debris from the tank before installing the replacement module.

E4042M Installation Notes

Record the VIN, RPO, cab, bed, wheelbase, and tank information before removal. Relieve fuel pressure, disconnect the battery, support and clean the tank, and compare the modules. Use the correct seal and verify lock-ring engagement. After installation, prime the system, confirm fuel pressure, inspect for leaks, confirm gauge operation, and recheck the electrical circuit.

Before Ordering the E4042M Fuel Pump Assembly

• Confirm a 2011–2016 Silverado or Sierra 2500 HD/3500 HD
• Verify the 6.0L gasoline V8; do not use for diesel applications
• Confirm the approximately 6.5-foot bed and non-Cab & Chassis configuration
• Match E4042M or the applicable OE/interchange number
• Compare tank, connector, module height, sender, float arm, seal, and retaining hardware
