Fuel pump replacement may be needed when a 2005–2006 Toyota Tundra 4.0L V6 or 4.7L V8, or a 2005–2007 Toyota Sequoia 4.7L V8, develops extended cranking, stalling or loss of power under load. No single diagnostic trouble code proves that the in-tank pump has failed: fuel-delivery complaints and fuel-level faults require separate electrical and mechanical tests. Symptoms, an illuminated check-engine light or an incorrect fuel gauge alone are not a reason to buy a pump.
This guide concerns the gasoline pump-and-sender module, not an engine-mounted pump or a fuel-pressure sensor. Confirm the exact vehicle configuration, original module number, connections and tank arrangement before ordering. A pickup and an SUV can share a replacement module without sharing every access step, tank mounting detail or fastener specification.
Advanced; safe gasoline handling and fuel-system diagnosis required.
Allow a full workday and contingency time. This is a planning allowance, not factory labor time.
$150–$350 for a replacement module; seller prices and configuration can differ.
Featured replacement module
A-Premium APFP0198 is the selected fuel pump module, ASIN B07GBDN4VJ, supplied as one assembly. The listing identifies a pump, sending unit, strainer and seal ring. The manufacturer also lists a float and gasket, but does not include a fuel-pressure sensor. Compare everything in the delivered package with the original assembly before dismantling the vehicle. Catalog cross-references include 77020-0C061 and E8694M; a cross-reference is a purchasing aid, not a substitute for a vehicle-specific match.

Vehicle compatibility
| Vehicle | Model years | Engine | Purchase check |
|---|---|---|---|
| Toyota Tundra | 2005–2006 | 4.0L V6 or 4.7L V8 | Match original module, connectors, fuel outlets and tank configuration. |
| Toyota Sequoia | 2005–2007 | 4.7L V8 | Confirm VIN-specific catalog match and sender arrangement. |
These are the applications identified for this product, not a claim of compatibility with every Toyota truck. Do not extend Tundra coverage to 2007, or assume a 2000–2004 truck accepts the module because an access video covers the same generation. Have the supplier resolve any disagreement between the catalog and the original part before installation. Do not modify electrical plugs or bend fuel pipes to make an uncertain replacement fit.
Symptoms and diagnosis before removal
Separate the complaint into three questions: does the engine receive fuel at the required pressure and volume, does the pump receive the required electrical supply, and does the gauge report fuel level correctly? Record stored and pending codes and freeze-frame information before clearing anything. Use the exact engine’s diagnostic definitions rather than a generic online code list.
Hard starting and poor performance are not unique to a pump. Check the available fuel, battery condition, ignition and engine-management inputs alongside fuel delivery. For a suspected electrical problem, examine the appropriate fuses, control circuit, grounds and connector condition. A voltage-drop test under operating load is more informative than assuming an unloaded voltage reading proves the wiring is healthy. Do not bridge unidentified terminals or bypass safety controls.
Pressure testing requires the correct gasoline-rated equipment and Toyota-compatible connection method. Compare results with the specification and test conditions for the actual engine; an idling pressure reading does not automatically establish delivery under load. Do not loosen a fuel line to judge pressure by the spray. A gauge-only complaint needs sender-circuit diagnosis, while a strong fuel smell needs a leak inspection before the vehicle is driven.

Replace damaged or one-time-use items; do not use generic sealant to compensate for a poor fit. |
DIY versus professional cost planning
For illustration, budget $150–$350 for a module and $20–$80 for minor consumables or hardware: a $170–$430 parts-and-consumables scenario when existing equipment is suitable. New tools, safe tank-support equipment, tax, shipping and unexpected corrosion repairs are additional. These figures are budgeting assumptions, not current product prices.
A sample shop calculation using $200–$500 for parts, $20–$80 for consumables and three to five billed hours at an assumed $120–$180 per hour gives $580–$1,480 before tax or additional repairs. Neither the hours nor the hourly rates are a Toyota labor-time specification or a guaranteed local quote. Ask whether diagnosis, tank cleaning, seal replacement and the final leak test are included.
Replacement planning and work sequence
Establish the complete procedure before disassembly. Obtain the Toyota instructions for the model, engine and tank arrangement, including pressure relief, access, retention, fastener tightening and post-repair testing. The following explains the sequence and stopping points; it does not assign the same tank access or torque to both vehicles.
- Confirm the fault and replacement. Finish the electrical and delivery tests, then compare the ordered module with the original application. Resolve differences before opening the fuel system.
- Prepare for gasoline handling. Cool the vehicle, remove ignition sources and prepare containment. Reduce the fuel load only with approved transfer equipment and containers. Relieve injection pressure by the vehicle procedure, then isolate electrical power.
- Establish access for the specific body. Use the applicable service route. Do not cut a hole through a bed or floor. When tank lowering is required, support and restrain the tank before releasing its mounts; keep the vehicle on independent approved supports.
- Release connections without strain. Identify and mark hoses and wiring. Clean their surroundings, release the correct retainers and contain residual fuel. Lower a supported tank only enough to reach remaining connections; never suspend it from hoses or wiring.
- Clean the module area. Keep dirt out of the tank. Remove the retainer using the prescribed method and lift the assembly carefully so the float arm is not bent. Protect exposed openings and inspect the tank for contamination or damage.
- Compare and install. Check flange shape, outlets, electrical keying, sender travel and sealing surfaces. Install the correct new seal in its specified position. Align the module as required and keep the float free of interference. Do not add unapproved grease, adhesive or sealant.
- Secure and reconnect. Tighten the module retention and tank mounting hardware using their separate specified values and sequences. Refit fuel connections and retainers positively. Restore routing, protective covers and any disturbed supports without pinching a hose or harness.
- Test before driving. Restore power only after the system is closed and spilled fuel has been dealt with. Prime by the vehicle procedure, inspect every disturbed connection and verify delivery and gauge operation. Shut down for wetness, persistent fuel odor or abnormal operation; do not road-test an unresolved leak.
Common mistakes
A similar-looking module is not necessarily the right one. Other costly mistakes include replacing the pump for a wiring fault, extending fitment from an older repair video, reusing a flattened seal, contaminating the open tank, forcing line locks, trapping the sender float and confusing inch-pounds with foot-pounds. Repeatedly replacing a pump without correcting its electrical supply or contaminated fuel does not address the original cause.
Frequently asked questions
Does this fit a 2007 Tundra?
The featured listing identifies 2005–2006 Tundra applications. Its 2007 coverage is for the listed Sequoia, not a 2007 Tundra.
Does it include the fuel-pressure sensor?
The manufacturer says no. Identify the failed component before assuming a complete pump module includes every fuel-system sensor.
Will replacement fix an inaccurate gauge?
Only if the sender/module is the cause and the replacement matches the circuit and tank. Wiring, connectors and gauge-related faults still need diagnosis.
Can I reuse the old seal?
Plan on the correct replacement seal. Inspect the supplied gasket and use the vehicle’s sealing instructions rather than attempting to repair a damaged seal with adhesive.
Is a general Tundra video a complete installation guide?
No. A strainer video can help explain access, but it is not proof of module compatibility or of every specification for another year, engine or Sequoia body.
