The stock pump flows about 3.5 LPM, and when it falls behind the high pressure pump starves and rail pressure drops under load.\u003c\/p\u003e\n\u003cp\u003eThe Precision Raceworks F-Series S55 High Performance Fuel Pump keeps the genuine OEM brushless pump in a genuine OEM bucket and adds a boost-activated Walbro pump on the outside of the bucket. Stage 3 is a plug-and-play drop-in for up to 900 whp. Stage 4 and 4.5 add AN-6 PTFE feed lines, a fuel pressure regulator, return lines and an inline filter, making them a complete low pressure fuel system for 1000+ whp builds.
