This large bore also dampens backpressure pulses created by larger injectors and works perfectly with stock injector sizes. An additional 1\/8th NPT port is included to accommodate a nitrous set up or fuel pressure gauge. A custom fuel line fitting is included for the factory fuel line, and in most cases the ends of each rail are pre tapped to accept -6 AN or 9\/16\"x18 fittings for users who want to use custom fuel lines.\nHigh Volume Fuel Rail, Black Anodized, Fits Mitsubishi 4G63 engine\n\u003cul\u003e\n  \u003cli\u003eNo additional parts required for installation - installs with factory fuel line using supplied fitting\u003c\/li\u003e\n  \u003cli\u003eComprehensive installation instructions, hardware, fittings and injector O-rings included\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch bore dampens backpressure pulses from larger fuel injectors\u003c\/li\u003e\n  \u003cli\u003e1\/8 NPT port included for nitrous pick up or fuel pressure gauge\u003c\/li\u003e\n  \u003cli\u003eComplete hardware, fittings and injector O-rings included\u003c\/li\u003e\n  \u003cli\u003eWorks with factory fuel line or custom fuel lines\u003c\/li\u003e\n  \u003cli\u003eSpecifically engineered for each application\u003c\/li\u003e\n  \u003cli\u003ePre-tapped for -6 AN or 9\/16\"x 18 fittings\u003c\/li\u003e\n  \u003cli\u003eSupports fuel flow up to 1,000 horsepower\u003c\/li\u003e\n  \u003cli\u003eBlack anodizing with laser engraving\u003c\/li\u003e\n  \u003cli\u003eCNC Machined from billet aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe AEM 25-131BK High Volume Fuel Rail is engineered for Mitsubishi 4G63 applications, including the 2005-2006 Mitsubishi Lancer Evolution VIII and Evolution IX.
