The Kozmic mechanical fuel pump kit is ready to provide all the fuel you could ever ask for. Includes everything needed for installation other than the crank pulley (works with fluidamper or ati - You MUST ALREADY HAVE ONE OF THESE, if not we do sell them as well) and building the lines for plumbing. Sold optionally with no pump or regulator for the guys who may have them laying around already.
Our kit includes a new lightweight pump driven pulley that is drastically lighter than most kits using the off the shelf aeromotive steel hub pulley. We also opted to use the HTD tooth pattern belt for great engagement and strength at high rpm. Tested vigorously to 9500 rpm, this kit was on the outlaw winning car during 2019 Subaru Nationals.
