AAM Competition E85 Fuel System Kit – Nissan 370Z & Infiniti G37 VQ37VHR Dual Pump Return Style

Unlock the full potential of your VQ37VHR on E85 with the AAM Competition Fuel Kit engineered for 2009-2020 Nissan 370Z and 2008-2013 Infiniti G37 platforms because factory fuel systems were never designed for ethanol and stock 275cc injectors, single in-tank pump, and restrictive returnless hardlines can’t supply the 30-40% more fuel volume E85 requires which leaves you with dangerous lean conditions, maxed-out injector duty cycles at just 350-380whp, and huge power left on the table, so this AAM Competition kit replaces every weak link with a complete motorsport-grade overhaul built for 500-800+whp boosted VQ37s, NA high-compression builds, and dedicated E85 street/track cars using E85-compatible Injector Dynamics ID1050x or DeatschWerks 1000cc injectors with stainless internals and Viton seals that provide stable spray patterns and linear low-pulsewidth control for perfect idle plus headroom for 750whp+ on ethanol, a CNC-machined billet aluminum dual pump fuel hat assembly with twin Walbro 450lph E85 pumps where the primary runs full-time and the second stages via Hobbs switch or ECU output under boost for seamless 900lph total flow with upgraded bulkhead wiring and check valves, a full return-style conversion that deletes the restrictive OEM returnless design using -8AN PTFE feed and -6AN PTFE return lines with black nylon braid that are 100% ethanol compatible and won’t degrade or permeate like rubber, CNC 6061 billet fuel rails with -8AN ORB ports and increased internal volume to eliminate restrictions and dampen injector pulses for stable pressure at each cylinder, an Aeromotive 1:1 boost-reference fuel pressure regulator that maintains consistent rail pressure from idle to 8000rpm at 25psi boost, plus 10-micron stainless and 100-micron billet E85-safe inline filters to protect pumps and injectors, all connected with black anodized swivel AN fittings and a complete dual relay harness with 10ga wiring, fuses, and Hobbs switch, delivering true E85 support for any ethanol blend without corrosion or pressure drop while gaining 40-60whp on NA builds and 80-120whp on boosted setups from E85’s 105 octane and charge cooling effect, keeping injector duty cycle under 80% even at 750whp and holding target pressure without falloff in 4th gear or fuel temp spikes during 20-minute track sessions, with full injector latency data and base pressure specs included for your tuner, fitting 2009-2020 370Z Coupe/Roadster, 2008-2013 G37 Coupe/Sedan/Convertible, and 2014-2015 Q60 3.7L VQ37VHR models only, making it the one-and-done fuel system for turbo or supercharged builds, high-compression NA E85 cars, and flex fuel setups where you need consistent AFRs lap after lap, because E85 is free octane and cooling but only if you can deliver the volume and this AAM kit does it right with proven components used on 8-second 370Z drag cars and championship time attack cars.
