Fuel Pump Module Assembly E3705M For 2005-2007 Chevrolet Tahoe/GMC Yukon V8 5.3L Engine 5.3L/V8

Extended cranking, low measured fuel pressure, hesitation under load, intermittent stalling, an EVAP-related fault, or an inaccurate fuel gauge can indicate an in-tank module problem after the fuse, relay, power supply, ground, wiring, and fuel lines have been tested. This E3705M replacement module is intended for specified 2005–2007 Chevrolet Tahoe and GMC Yukon 5.3L V8 flex-fuel applications. Confirm the fuel type, OE number, two electrical connectors, fuel-line layout, pressure-sensor configuration, flange, module height, and float-arm geometry before ordering.

Flex-Fuel Pump Module Fitment for Tahoe and Yukon

Verified coverage is limited to selected 2005–2007 Tahoe and Yukon 5.3L V8 flex-fuel configurations. A gasoline-only module or an assembly with different connectors, fuel ports, tank-pressure sensor, sender calibration, or reservoir depth is not interchangeable solely because the model and year match.

Fitment Verification

• Confirm a 2005–2007 Chevrolet Tahoe or GMC Yukon with the 5.3L V8 flex-fuel system.
• Match E3705M, FG0816, SP6087M, P77007M, 19133546, 19133578, 19168418, 19168419, 19208960, 19208961, or 88965802.
• Compare the four-terminal and three-terminal electrical connectors with the removed module.
• Verify the fuel-line connections, pressure-sensor arrangement, flange, reservoir, module height, and float-arm direction.

Module Functions and Service Components

• Electric in-tank pump supplies fuel to the engine-side delivery system.
• Fuel-level sending unit and float arm report tank level to the instrument cluster.
• Pressure-sensor, reservoir, inlet strainer, and tank-seal functions must match the original assembly.
• Sender calibration is approximately 43 ohms at empty and 257 ohms at full in applicable catalog data; verify against the original module.

Symptoms and Diagnostic Checks

Measure fuel pressure before replacing the module. Test voltage and ground at the module under load, inspect the fuse and relay, and check the two connectors, fuel lines, sender circuit, and tank-pressure sensor. A flex-fuel mismatch, restricted line, damaged wiring, EVAP fault, tank contamination, or engine-management problem can produce similar symptoms.

Installation Notes

Relieve fuel-system pressure, disconnect the battery, and support the tank safely. Clean the tank and sealing surface, install the correct new seal and approved service hardware, keep the float arm clear, and reconnect each line and connector correctly. Prime the system, inspect the flange and lines for leaks, measure fuel pressure, scan the pressure-sensor circuit, and confirm normal gauge operation.
