ATS Racing Top Feed Fuel Rail Installation Kit includes -6 fuel feed line, adapter fitting for stock Toyota fuel filter, and bushing that allows installation of stock fuel pressure regulator on the ATS Racing Top Feed Fuel Rail. For users under 500whp this kit saves over $200 versus buying fittings, lines and an aftermarket regulator, plus it makes installation easy. Dyno tested to 550whp. Fits Gen 2 and Gen 3 ATS Top Feed Rails. Now includes injector connectors too!
Update - the stock regulator (and ATS blueprinted regulator) have been tested up to 550whp using Walbro 255 or Bosch 044 pumps. But for those going for higher horsepower numbers and using dual fuel pumps the stock regulator will not flow enough at idle. For you we have added the option of a larger aftermarket regulator.
