Fuel Pump Install Kit

Time for more fuel? Look no further than the new K27 Fuel Pump Kit! Our mission on this product was simple - Quality and Performance. This kit will allow you to install your choice of fuel pump in place of the OEM pump on the EvoX or Ralliart with no modification. Just check out or key features below and you will know this is the kit for you.

What pump should I choose?

Walbro 255

  • Great for 93 Octane applications when running less than 500hp.
  • Known here as "Old Reliable", they have the lowest failure rate of any fuel pump we have ever used.
  • Perfect for E85 applications on stock turbo, or larger turbos.

Walbro 450

  • Simply put, when you need more than the 255 can bring - this pump is for you.
  • Works great with 93 octane or E85.
  • Stable at high PSI, meaning with a adjustable regulator, you can squeeze all that is possible from a slightly too small set of injectors you need to upgrade!
  • Fuel pressure gauge is recommended. Due to this pumps higher flow ratings, signs of restricted or dirty return filters may show with elevated base pressure.


  • Billet Aluminum Pump Holder - Anodized to be ALL FUELS SAFE (Including Methanol and Ethanol)
  • Precision CNC Cut for perfect fitment
  • High quality stainless hardware
  • PTFE Fuel Line - ALL FUEL SAFE
  • Exact OE Fitment - No basket modification needed
  • Indication Arrow for fuel pump orientation, no guess work needed


  • 2008-2016 Mitsubishi Lancer Evolution X

Awesome fuel pump, easy install!

I installed this back in January 2019. Super easy install and the Kozmic kit is high quality. Currently tuned for flex fuel 91/E85, pump has no issues! Highly recommended


This kit seems well thought out. Except for having to cut off the factory supply line to make way for the larger replacement that comes with the kit this kit allows for you to pretty much unbolt and keep your stock pump in tack which is nice if you every wanted to reinstall. My adapter had one minor defect. one of the threaded holes in the adapter had a minor defect but was easily fixed with a tap. Instructions for installation can be found on Kozmic Motorsports website and they are easy to fallow.
