Description: This Driven Diesel Regulated Return Kit is a must - have for 2003 - 2007 Ford F - Series and Excursion vehicles with 6.0L Powerstroke engines. It's a key part of upgrading your fuel system. First, it gets rid of the 'dead - head' stock fuel rails and allows you to adjust the fuel pressure. On top of that, the included Fuel Bowl Delete Kit boosts fuel flow by removing the restrictive stock fuel filter. The main advantage? A huge increase in fuel flow through the heads, so your fuel injectors always have enough fuel volume and pressure, no more 'Wide Open Throttle Pressure Drop'. If you want longer injector life, less noise, especially when installing new injectors (stock or aftermarket), we highly recommend this kit to safeguard your investment. Part Number: DD - 60FS - FBD - RRK - V3. Features: It clears stock and aftermarket turbocharger setups, creates more space in the engine valley, doesn't interfere with intercooler tubes, fits both single and dual alternator engines. It comes with an exclusive custom return fitting, high - flow banjo bolts, a new Ford fuel bowl fitting O - ring, a high - quality FueLab bypass fuel pressure regulator, a stainless - steel regulator mounting bracket, a fuel pressure gauge, custom CNC bent hard lines, and high - quality braided Teflon fuel lines. The kit includes all necessary parts and detailed instructions, plus a special long - handled 6mm Allen tool.
