E3962m Fuel Pump Module Assembly For Chevrolet C2500/C3500/K2500/K3500, Gmc C2500/C3500/K2500/K3500 V8 5.0l, V8 5.7l

E3962M Fuel Pump Module for 1998–2000 Chevrolet and GMC C/K 2500/3500 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 E3962M electric fuel pump module assembly is an aftermarket replacement for specific 1998–2000 Chevrolet and GMC C2500, C3500, K2500, and K3500 gasoline trucks. The verified engines are 5.7L and 7.4L V8 configurations, not the 5.0L engine shown in the previous description. Confirm the module code, emissions package, tank, connector, and OE number before installation.

Confirm E3962M Truck and Engine Fitment

• 1998–2000 Chevrolet C2500 and C3500 with the 5.7L or 7.4L V8 engine
• 1998–2000 Chevrolet K2500 and K3500 with the 5.7L or 7.4L V8 engine in matching configurations
• 1998–2000 GMC C2500 and C3500 with the 5.7L or 7.4L V8 engine
• 1998–2000 GMC K2500 and K3500 with the 5.7L or 7.4L V8 engine in matching configurations

Module Code and Emissions Restrictions

Applicable 1998–1999 configurations commonly require module code GFT and no radio-frequency interference filter, including the relevant RPO 8J9 configuration. For 2000 models, confirm the emissions label because certain references exclude California-emissions vehicles. Cab, chassis, tank capacity, and tank position must also match.

E3962M OE and Interchange Number Check

Listed references include E3962M, P74768M, FG0085, SP6145M, F3973A, MU1752, MU1282, MU145, 19177240, 19177242, 19331271, 19332100, 19369941, 19369942, 25314020, 25314024, 25314319, and 25314335.

Comparable P74768M specifications include the fuel-level sender, internal strainer, and seal, but do not include a fuel-tank pressure sensor or lock ring. Compare the module code, connector, line fittings, housing height, pickup, sender arm, seal, and retaining arrangement with the removed assembly.

Check the Truck Fuel System Before Replacing E3962M

• 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, regulator, and injectors
• Test the fuel-level sender and gauge circuit separately when the gauge is inaccurate

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

E3962M Installation Notes

Relieve fuel pressure, disconnect the battery, record the module code and tank configuration, support and clean the tank, and compare both modules. Use the correct seal and verify retaining-ring engagement. After installation, prime the system, verify fuel pressure, inspect every connection and the tank seal for leaks, confirm gauge operation, and recheck the electrical circuit.

Before Ordering the E3962M Fuel Pump Assembly

• Confirm a 1998–2000 C2500, C3500, K2500, or K3500 with a 5.7L or 7.4L gasoline V8
• Do not use the previous 5.0L engine statement
• Verify GFT module code, RFI-filter configuration, RPO, and emissions label
• Match E3962M or the applicable OE/interchange number
• Compare tank, connector, module height, sender, float arm, seal, and retaining hardware

This is a BDFHYK aftermarket replacement fuel pump module assembly, not a Chevrolet, GMC, or GM factory OEM component.
