📝 Product Description

The 77020-08070 is a genuine Toyota fuel suction tube assembly incorporating the electric fuel pump and fuel gauge sending unit.

Toyota parts catalogs identify the component as:

“Tube Assy, Fuel Suction W/Pump & Gage”

and dealer catalogs further specify that the assembly includes the fuel tank sending unit and is an in-tank unit for the Sienna 3.5L application.

The part is primarily associated with the 2016–2020 Toyota Sienna XL30 equipped with the 3.5L V6, but the exact OE suffix depends on vehicle production date. Toyota catalogs show 77020-08070 and 77020-08071 as separate fuel suction tube assemblies, so they should not be treated as universally interchangeable.

⚙️ Core Functions

• ⛽ Delivers gasoline from the fuel tank to the engine fuel system.

• 🔌 Uses an electric in-tank fuel pump.

• 📊 Provides fuel-level information through the integrated sending unit.

• 🔧 Combines fuel suction tube, pump and gauge-sending functions.

• 🛡️ Provides an OE-style replacement for selected Toyota Sienna applications.

• 🔁 Directly references Toyota OE 77020-08070.

⚠️ Common Failure Symptoms

A worn or failed fuel pump assembly may cause:

• Difficult engine starting

• Extended cranking

• Intermittent no-start condition

• Engine stalling

• Hesitation during acceleration

• Reduced fuel delivery

• Poor engine performance under load

• Abnormal fuel-pump noise

• Fuel gauge reading problems

• Intermittent fuel-level indication

⚠️ These symptoms can also be caused by electrical wiring, relays, fuel pressure problems, fuel contamination or other fuel-system components. Diagnose the vehicle before replacing the pump.

🔁 OE & Cross ReferenceMain Toyota Fuel Pump Assemblies

• 77020-08050 — earlier Sienna fuel suction tube assembly

• 77020-08071 — later/related Sienna fuel suction tube These related numbers should not automatically be advertised as interchangeable. Toyota's catalog separates the assemblies by production date and vehicle configuration.

  * Important: The year-only table above should not be interpreted as blanket fitment. Toyota parts catalogs provide production-date restrictions for 77020-08070, while 77020-08071 is used for another production range. Verify the vehicle production date and original OE number.

  📅 Production-Date Fitment

  This is the more important catalog information for this OE:

  OEApplicationProduction Date Information77020-08070Toyota Sienna 3.5LSelected production periods beginning around 08/201677020-08070Toyota Sienna 3.5LCatalog data extends through selected production periods in 2017–202077020-08071Toyota Sienna 3.5LLater production configuration77020-08090 / 08091Toyota SiennaLater-generation / later-production applications

  Toyota's parts catalog specifically lists 77020-08070 alongside production-date information and separately lists 77020-08071. An aftermarket module guide likewise separates 77020-08070 for 2017–2019 from 77020-08071 for 2019–2020.

  🚫 Non-Fitment / Important Warnings

  ❌ Do not automatically apply 77020-08070 to every Sienna.

  ❌ Do not assume every 2016–2020 Sienna uses 77020-08070.

  ❌ Do not automatically substitute 77020-08071.

  ❌ Do not use this OE for the 2021+ Sienna generation.

  ❌ Do not use this listing for the Sienna Hybrid unless the original OE number matches.

  ❌ Do not assume the assembly fits other Toyota models merely because some aftermarket pumps share cross-reference numbers.

  ⚠️ Some aftermarket replacement products cross-reference 77020-08070 to Toyota Highlander applications, but the genuine Toyota OE catalog evidence reviewed here identifies 77020-08070 specifically as a Sienna fuel suction tube/pump & gauge assembly. Therefore, for an OE catalog listing, Sienna should remain the core application.

  🔧 Installation & Quality Notes

  • Compare the original OE number before installation.

  • Check the vehicle production date.

  • Verify the engine is the 3.5L V6.

  • Compare the electrical connector.

  • Compare the fuel-line connection.

  • Compare the mounting flange and pump-module shape.

  • Inspect the fuel tank for dirt or contamination.

  • Replace the tank seal if damaged or specified for replacement.

  • Ensure all fuel-line connections are securely locked.

  • Prime the fuel system after installation.

  • Check for fuel leakage before starting the engine.

  • Verify the fuel gauge operates correctly after installation.
