Designed for E-chassis models targeting up to 650 whp, this in-tank LPFP solution retains the factory pump for everyday use and adds a secondary pump that activates under boost to support increased flow while maintaining OEM-like drivability.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eSupports builds up to 650 whp on BMW N54 and N55 E-chassis platforms\u003c\/li\u003e\n  \u003cli\u003eSecondary in-tank pump runs in parallel with the stock unit to add up to 200% more low-pressure fuel capacity\u003c\/li\u003e\n  \u003cli\u003eNo modification to the factory bucket, wiring or fuel lines and fully reversible\u003c\/li\u003e\n  \u003cli\u003eReduces strain on the OEM wiring and EKP and is designed to help avoid iDrive fuel pressure warnings\u003c\/li\u003e\n  \u003cli\u003eChoose your pump: Walbro 450 F90000274 or optional Walbro 525 F90000285\u003c\/li\u003e\n  \u003cli\u003eAvailable with or without a new stock LPFP, plus optional new tophat and optional secondary pump wiring harness\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eHow it works: the kit utilises your factory LPFP assembly for normal driving. Under boost, the added Fuel-It! secondary pump switches on to deliver the extra flow your tuned engine demands. Because the system runs the secondary pump independently, there is no added load on the OEM controller.\u003c\/p\u003e\n\n\u003cp\u003eIf you already run a Fuel-It! Stage 2 setup, this kit can be added to upgrade your system further.\u003c\/p\u003e\n\n\u003ch3\u003eControl and setup\u003c\/h3\u003e\n\u003cp\u003eThe secondary pump must only operate under boost, not continuously. We recommend triggering it with a Hobbs switch (15 psi is common, or 4 psi if you generate strong torque at lower boost). Some newer BMS port injection controllers can also provide the trigger signal.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eWalbro 450 pump F90000274 (optional upgrade to Walbro 525 F90000285)\u003c\/li\u003e\n  \u003cli\u003eBlack anodised custom fitting and pump brackets\u003c\/li\u003e\n  \u003cli\u003eFuel line and replacement clip\u003c\/li\u003e\n  \u003cli\u003e9\/64 inch terminals with associated hardware\u003c\/li\u003e\n  \u003cli\u003eSecondary pump wiring harness (optional)\u003c\/li\u003e\n  \u003cli\u003eNew tophat (optional)\u003c\/li\u003e\n  \u003cli\u003eNew stock pump assembly (optional)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eFitting notes: installing the upgrade requires adding two 9\/64 inch power terminals to the tophat.
