The factory pump is controlled by PWM designed to reduce output once target fuel pressure (typically 5 bar) is reached — which puts it in constant conflict with any upgraded or added pump trying to feed port injection. On top of that, the high-pressure pump's control system dumps fuel back into the low-pressure system at high pressure\/low volume, causing pressure oscillations that limit how consistently an upgraded pump can perform.\u003c\/p\u003e\n\u003cp\u003eThe Precision Raceworks Stand Alone AFS™ (Auxiliary Fuel System) solves this at the source: instead of trying to make the factory low-pressure system do double duty, it adds a completely dedicated, independent fuel system just for your port injection setup. Instructions are similar to the G8x\/G2x kits.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDedicated system:\u003c\/strong\u003e A fully separate low-pressure fuel system for port injection — completely independent of the factory pump and its PWM control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBillet top hat:\u003c\/strong\u003e Billet aluminum top hat with 3 high-flow fuel ports\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully adjustable regulator:\u003c\/strong\u003e 1:1 boost-scalable billet fuel pressure regulator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiltration:\u003c\/strong\u003e 10-micron USA-made Microglass fuel filter, ideal for E85\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLines:\u003c\/strong\u003e Smooth-bore, high-flow PTFE feed and return lines (AN6)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump Selection:\u003c\/strong\u003e AFS.460 — single Walbro 535, 460 LPH @ 3 bar; AFS.640 — dual Walbro 450s, 640 LPH combined @ 3 bar; AFS.800 — dual Walbro 535s, 800 LPH combined @ 3 bar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100% ethanol compatible:\u003c\/strong\u003e All components rated for full E85 compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWalbro fuel pump(s) per selected configuration\u003c\/li\u003e\n\u003cli\u003eBillet aluminum top hat and fuel pressure regulator\u003c\/li\u003e\n\u003cli\u003e10-micron Microglass fuel filter\u003c\/li\u003e\n\u003cli\u003ePTFE feed\/return lines and fittings\u003c\/li\u003e\n\u003cli\u003eConfigurable pump activation harness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for use with a port injection kit where the fuel rail is mounted above the manifold.
