Walbro / TI Automotive Fuel Pump Installation Kit | Application-Specific | All Installation Components Included

The Walbro / TI Automotive Fuel Pump Installation Kit (400-842) is an application-specific fuel pump installation kit engineered for installing TI Automotive high-performance fuel pumps — including all required installation components for a complete, correct fuel pump installation. Fuel pump not included — this kit contains the installation hardware only. TI Automotive's installation kits are designed to complement their GSS-series and other high-performance in-tank fuel pumps — providing the correct strainer, wiring harness, and fittings for a direct-fit, race-proven installation. TI Automotive is the manufacturer of Walbro-branded fuel pumps and fuel system components — over 60 years of fuel system engineering heritage.

Key Features:

• Application-specific design — engineered for a specific vehicle application — correct strainer dimensions, wiring connector type, and fitting sizes for the specific application — verify fitment for your specific vehicle before ordering
• All installation components included — complete installation kit with all required hardware for a correct fuel pump installation — no additional components required beyond the fuel pump itself
• Race-proven design — TI Automotive's installation kit technology is developed for high-pressure, high-flow engine applications — correct for performance builds using TI Automotive's GSS-series and other high-performance fuel pumps
• Direct-fit replacement design — engineered as a direct-fit replacement for the specific application's factory fuel pump installation hardware
• Fuel pump not included — this kit is the installation hardware only — the fuel pump (e.g., Walbro GSS340 255lph) must be sourced separately
• TI Automotive / Walbro quality — manufactured by TI Automotive, the builder of Walbro-branded fuel system components for over 60 years

What's Included:

• Fuel pump strainer (sock filter) — application-specific strainer for correct pump inlet filtration
• Wiring harness — correct connector type and wire gauge for the specific application
• Fuel line fittings and hardware — all required fittings for correct fuel line connections
• All additional installation hardware required for a complete installation
• Fuel pump not included — must be sourced separately
• Refer to TI Automotive's product documentation for the complete and current kit contents list

Fuel Pump Not Included — Pairing Guide:

This installation kit is designed to be used with TI Automotive's high-performance in-tank fuel pumps — most commonly the Walbro GSS340 255lph high-pressure in-tank pump. The installation kit provides the correct strainer, wiring, and fittings for the specific application — the fuel pump provides the flow and pressure. Both components are required for a complete fuel pump upgrade installation. The Walbro GSS340 255lph pump (WALGSS340G3) is available separately.

Specifications:

• Brand: Walbro / TI Automotive
• Part Number: WAL400-842
• Barcode: 400-842
• Type: Fuel pump installation kit — application-specific
• Contents: All installation components — fuel pump not included
• Weight: 0.7 lbs (kit only)

Fitment Information:

• Application-specific — verify fitment for your specific vehicle before ordering
• Confirm that WAL400-842 is the correct installation kit for your specific vehicle application and fuel pump model before ordering — TI Automotive's part number lookup tool or your vehicle's service documentation will confirm the correct kit
• Note: Fuel pump not included. Verify application fitment before ordering. Professional installation by an experienced fuel system specialist recommended.

Installation Notes:

• Professional installation by an experienced fuel system specialist recommended — fuel pump installation requires correct fuel system depressurization, correct wiring connections, and correct fuel line connections before the fuel system is pressurized
• Always replace the fuel pump strainer (included in this kit) when replacing the fuel pump — a new strainer is essential for correct pump operation and longevity
• Verify correct wiring polarity before installation — reversed polarity will damage the fuel pump immediately
• Prime the fuel system before the first start — cycle the ignition on and off several times to build fuel pressure before cranking the engine
• Check for fuel leaks at all connections after installation and after the first heat cycle

Why Walbro / TI Automotive?

TI Automotive has been building fuel pumps and fuel system components under the Walbro brand name for over 60 years — a heritage of reliability, performance, and first-time fit that makes Walbro the most trusted name in performance fuel pumps. TI Automotive's installation kits are engineered to the same standard as their fuel pumps — correct components, correct fitment, and correct quality for a complete, reliable fuel pump installation. For performance builds using Walbro fuel pumps, TI Automotive's application-specific installation kit is the correct companion component.

Perfect For:

• Performance builds using Walbro / TI Automotive in-tank fuel pumps (GSS340 and others) where a complete, application-specific installation kit with strainer, wiring, and fittings is required for a correct installation
• Fuel pump upgrades where the factory installation hardware is being replaced alongside the pump for a complete, fresh fuel system installation
• Builders who want TI Automotive's race-proven installation kit technology for a correct, reliable high-performance fuel pump installation

Note: Fuel pump not included — must be sourced separately. Application-specific — verify fitment for your specific vehicle before ordering. Professional installation recommended. Prime fuel system before first start. Check for leaks after installation.
