The Precision Raceworks Ford Focus ST Low Pressure Fuel Pump Upgrade is designed for customers looking to run all blends of E85. The kit will include a Walbro 450 (F90000274) or Walbro 535 (F90000295)


Note: You Must Have a "PFS 1188 - Motorcraft Pump" for this Upgrade to Work


Our design was targeted to remove the need for sending your fuel pump assembly in for modification.  Following the provided instructions the average home mechanic can assemble and install our kit. This means less down time and a great reduction in both assembly & shipping cost as well. Best of all you end up with your pump in the condition it was in when you pulled it from the car and run no risk of getting a housing back that is in poor condition.

Install is easy there is no guess work on engagement and sealing of o-ring or complications and risks tightening clamps that can poke holes in critical plastic components near by.
