This fuel pump/filter upgrade kit is for the 2007+ Tundra ALL ENGINES.
The heart of the fuel system is the fuel pump. It must deliver the volume of fuel needed at the required pressure for the rest of the fuel system to do its job. If the pump can’t provide more flow, don’t expect to have the fuel needed for more power.
UNDERDOG RACING DEVELOPMENT has been making and tuning forced induction systems for the Toyota 4.0L 1GR-FE engine since 2005. One thing we observe time and time again is as the power levels go up, the fuel pressure starts to drop off. The stock in-tank fuel pump combo does not flow enough fuel to maintain sufficient pressure in the fuel rail.
The small in-tank fuel filter appears to become clogged in less than 30,000 miles restricting fuel flow resulting in insufficient flow/volume reaching the fuel rail. This can lead to a dangerous, lean fuel mixture. Until now, the only fix for this was to buy an entirely new “tank unit” from your local Toyota dealer. The fuel filter is not available separately and is only available as a complete tank unit that includes the plastic in-tank assembly with the fuel filter, fuel pump, and level float. This retails for around $575. We have been seeing the very same problem in the Tundra tank unit and the filter becoming flow restrictive. The design is very similar to the one on the Tacoma.
The URD 2007+ Tundra Fuel Pump/Filter Upgrade Kit fixes both problems, insufficient flow from the stock pump, and the problem of the stock fuel filter’s short service life before it becomes clogged and restrictive.
If you have converted your 2007+ Tacoma engine to any type of forced induction system, URD strongly recommends installing the URD fuel pump/filter upgrade kit.
URD gives you the option of what fuel pump you wish to run in your pump/filter conversion kit. You may pick from the AEM 320 LPH pump, AEM E85 320 LPH pump, the DeatschWerks 255 or 320 LPH pump, or the AeroMotive 340 LPH pump. If you wish to run E85 the DeatschWerks pumps are fully E85 compatible. The AEM and the AeroMotive pumps can be used with E85, but the manufacturer states that you should expect reduced pump life with the E85 fuel.
Note: This kit is not compatible with the FlexFuel trucks. The tank unit is different in those applications.
