Fuel Gas Pump Sending Unit ID Tag TCU For Sierra Silverado

When your Chevy Silverado or GMC Sierra starts hesitating, stalling, or simply refuses to fire up, a worn in-tank fuel pump and sending unit is one of the most common causes. The Mankee Fuel Pump & Sending Unit Assembly delivers a factory-style, direct drop-in solution that bundles the in-tank pump, float arm sender, ID tag, and TCU (transfer control unit) into a single complete module — so you fix the problem once, correctly, without chasing individual parts across multiple vendors. Compatibility This assembly is engineered to replace the OEM fuel pump module in Chevy Silverado and GMC Sierra pickup trucks across multiple model years and engine configurations. The Silverado and Sierra lineup spans a wide range of cab styles, bed lengths, fuel tank sizes, and engine displacements — from the 4.3L V6 base engine through the popular 5.3L V8 and the high-output 6.2L V8. Because variations in tank size and module mounting diameter can differ between trims, sub-models, and production runs, it is essential that you verify your specific year, sub-model, and OEM part number before installation. Check the ID tag on your factory pump module or cross-reference your VIN against a GM parts catalog. If you are unsure, contact our support team with your full VIN and we will confirm compatibility before your order ships — no guesswork required. Key Benefits • Complete drop-in module: pump, float sender, ID tag, and TCU ship together, eliminating the risk of mismatched components and reducing total parts cost. • Restores accurate fuel-level gauge readings by pairing a fresh float arm and calibrated variable-resistance sender with the new pump — no more phantom empty warnings. • Eliminates the symptom cycle of hard starts, rough idle, fuel pressure drop, and engine surging caused by a degraded OEM pump that no longer holds rated pressure. • Ethanol-compatible materials on all wetted components stand up to the E10 and E15 blends common at US pumps, extending service life versus budget alternatives. • Single-unit replacement reduces labor time significantly compared to sourcing and installing individual pump, sender, and TCU components separately. • Works for DIY garage installs and professional shop replacements alike, with plug-and-play electrical connectors designed to mate directly with factory GM wiring harnesses. Technical Specs • Application: Chevy Silverado and GMC Sierra pickup trucks (multiple model years; confirm via VIN) • Included components: in-tank fuel pump, float arm sending unit, ID tag, TCU (transfer control unit) • Engine compatibility: 4.3L V6, 5.3L V8, 6.2L V8 variants (verify by sub-model and tank size) • Connector type: OEM-matched GM plug-and-play electrical connector • Fuel compatibility: gasoline, E10, E15 ethanol-blended fuels • Mounting style: direct OEM drop-in, no modification required • Pressure rating: engineered to meet or exceed OEM fuel pressure specifications • Regulatory note: designed for on-road light-duty truck applications in the US market Materials & Build Quality The Mankee assembly uses corrosion-resistant materials across every wetted surface that contacts fuel. In an era when ethanol-blended fuels have become the default at most US gas stations, cheaper assemblies built with standard steel and low-grade polymers can corrode internally within two to three years, degrading fuel pressure and contaminating injectors. Mankee addresses this by selecting fuel-compatible polymers for the pump housing, float arm, and sender components, while the electrical connections are sealed against moisture intrusion that can cause resistance spikes and false fuel-level readings. The float arm geometry is calibrated to match the original GM sender sweep angle, ensuring the fuel gauge needle tracks accurately across the full tank range from empty to full. Every module is assembled to close tolerances to prevent internal leaks that would otherwise allow fuel vapors to accumulate in the tank sending-unit cavity. Installation Guide Installing this fuel pump module is a straightforward job for a competent DIYer with basic hand tools and a few hours of time. Begin by relieving fuel system pressure — locate the fuel pump fuse or relay in the underhood fuse box, start the engine, and let it stall to depressurize the lines. Disconnect the negative battery terminal. With the truck bed either removed or raised for access (depending on your model), disconnect the fuel filler neck vent hose and the fuel feed and return lines at the top of the tank using quick-disconnect tools. Unplug the factory electrical connector from the pump module. Using a GM-style lock ring spanner or a brass drift punch and hammer, rotate the locking ring counterclockwise and lift the old module out carefully to avoid bending the float arm. Note the orientation arrow on the lock ring before removal. Drop the new Mankee module into the tank, aligning the orientation arrow to the index mark on the tank collar. Rotate the new lock ring clockwise until fully seated and the tabs engage. Reconnect the fuel lines (they will click when locked), plug in the OEM electrical connector, reinstall the fuse or relay, reconnect the battery, and cycle the key to the ON position two or three times to prime the system before attempting a start. Check for fuel leaks at all connection points before returning the truck to service.
