It is the last piece of a port injection build, not a standalone upgrade.\u003c\/p\u003e\n\u003cp\u003eInstead of sharing the factory supply, the AFS puts its own pump or pumps in the tank and runs dedicated AN6 lines to the port injection rail. The factory primary pump is PWM controlled and backs off around 5 bar, and the high-pressure pump control pushes fuel back into the low side, so a shared supply oscillates. A dedicated system holds steady pressure that scales 1:1 with boost, which lets you run smaller port injectors, reduces how hard the DI system has to correct and makes the car easier to tune.\u003c\/p\u003e\n\u003cp\u003eThis is the complete kit including the billet top hat. Two flow ratings are offered here: AFS.460 with a single Walbro 535 and AFS.800 with dual Walbro 535 pumps. If your car already has the Precision Raceworks G-Series \/ Supra billet top hat, the AFS Upgrade Kit without the hat is the lower-cost route.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAFS.460 (601-0333): single Walbro 535 (F90000295), 460 LPH at 3 bar\u003c\/li\u003e\n\u003cli\u003eAFS.800 (601-0332): dual Walbro 535 (F90000295), 800 LPH combined at 3 bar\u003c\/li\u003e\n\u003cli\u003eBillet aluminum top hat with 3 high-flow fuel ports\u003c\/li\u003e\n\u003cli\u003eDedicated AFS pump(s) mounted in a slosh-resistant location, independent of the factory PWM-controlled primary pump\u003c\/li\u003e\n\u003cli\u003eFully adjustable 1:1 boost-referenced billet fuel pressure regulator\u003c\/li\u003e\n\u003cli\u003e10 micron USA-made microglass fuel filter, E85 rated\u003c\/li\u003e\n\u003cli\u003eAN6 smooth-bore PTFE feed and return lines with billet fittings\u003c\/li\u003e\n\u003cli\u003ePlug-and-play connectors inside and outside the top hat; configurable pump activation harness\u003c\/li\u003e\n\u003cli\u003eWorks with stock or upgraded primary fuel pumps; all components 100% ethanol compatible\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eComplete stand-alone auxiliary fuel system for the flow rating selected: billet top hat, AFS pump(s) on the mounting arm, adjustable 1:1 billet regulator, 10 micron microglass filter, AN6 PTFE feed and return lines, billet fittings, plug-and-play connectors and the configurable pump activation harness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eRequired Extras\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eA port injection kit with the fuel rail mounted above the intake manifold is required; the AFS feeds that rail and does nothing on its own: \u003ca href=\"\/products\/precision-raceworks-b58-port-injection-kit\"\u003ePrecision Raceworks B58 Port Injection Kit\u003c\/a\u003e.
