A failing fuel pump has many potential symptoms, including:

hard starting cold or after a heat soak
an illuminated check engine light
engine misfire under load or when cold
stalling
no-start.

This OEM Bosch in-tank fuel pump includes the pump and inlet strainer. This can be replaced easily by accessing the top of the fuel tank beneath the rear seat, no need to drop the fuel tank.

This part does not include the fuel level sensor. The fuel level sensor can be reused from the original fuel pump or a new sensor can be purchased under T#392738.

Enhance Fuel Pressure with Engine Bay Metal Pump

This metal pump, situated in the engine bay, is designed to boost pressure for the direct injection system. It includes a sealing O-ring and connects from the fuel feed to the fuel rail pressure line. Notably, this unit is equipped with the smaller spring.

Key Details:

• Enhances fuel pressure for direct injection systems
• Includes a sealing O-ring for a secure installation
• Connects from the fuel feed to the fuel rail pressure line
• Features the smaller spring unit for specific applications

Upgrade your engine's performance with this reliable metal pump.

These kits are designed to be installed inline with your stock low-pressure fuel pump (LPFP).  They provide approximately 50% more flow when combined with your stock pump.

Kit includes the following:

• SAE J30R10 E85 compatible fuel line
• 14ga fuel resistant wiring harness
• Quick connect female bullet connectors (2)
• Vent tube replacement clip
• Nylon cable ties (10)
• Stainless steel lock nuts (2)
• 10ga/14ga step-down butt splices w/E85 compatible heat-shrink tubing (2)
• Pushlock pump retention fittings (2)
• 14ga butt connectors w/heat-shrink tubing for pump removal to return to stock if/when desired (2)

  *Note:  Walbro does not warranty this pump for E85 use.  If your application requires an E85 certified pump you may want to consider selecting a Stage 2 fuel kit.

  ** IMPORTANT:  Do NOT attempt to run this kit inline with a Stage 2 kit.  The Stage 2 kit is a higher flowing kit and this will not only restrict the flow of the stage 2 kit, it will result in failures.

This is a complete plug and play solution to replace your stock Low-Pressure Fuel Pump (LPFP) with a new E85 certified bucketless assembly.

This solution provides up to 25% more flow than our standard Stage 2 LPFP upgrade and up to 150% more flow than the stock pump.  

This pump will support up to 550whp running 85% ethanol and 600whp running 50% ethanol. 

The Stage 2 bucketless kit includes the following:

• • A custom anodized billet fitting for the pump output and stock fuel line connection.
  • Our custom billet aluminum anodized bracket for the pump and float assembly
  • Two cotter pins to secure your float assembly
  • A new E85 compatible Walbro 450 pump
  • Spare vent tube clip
  • A new Walbro filter

If you still need more flow, the Stage 3 upgrade is also available and can be added to your Stage 2 bucketless pump.

The Stage 3 upgrade kit includes:

• • A complete plug and play solution by simply adding the secondary module
  • Our custom billet aluminum fitting to run both pumps in parallel
  • A new E85 compatible Walbro 450 pump
  • Wiring harness for the secondary pump
  • Spare vent tube clip
  • A new Walbro filter

• Recommended accessories:
  • Lock Ring Removal Tool
  • Hobb's switch 
     
• NOTE: These kits include a basic filter assembly.  When using this filter, running the vehicle under low fuel conditions can cause fuel starvation issues. If you do hard straight line accelerations when you have less than 1/8 tank of fuel, we would recommend running our standard Stage 2, 3, or Stage 4 pump.  In addition, if you intend to use this for road course applications, you may see starvation issues when running less than a half tank and doing long high G right turns.  Again for those applications we'd recommend one of our standard pump applications.
