Phantom Stealth Flex Fuel System Use w/E85

The Phantom Stealth Flex Fuel System Use w/E85 from Aeromotive is a high-flow electric in-tank fuel pump engineered for serious performance builders running alternative fuels or demanding forced-induction applications. Whether you're building a turbocharged, supercharged, or nitrous-equipped engine that requires consistent fuel delivery under extreme pressure spikes, this stealth pump delivers 450 liters per hour at 90 psi—enough capacity for naturally aspirated big-blocks and moderate boost applications. Built for the modern tuner who refuses to compromise on reliability, this pump handles both conventional gasoline and E85 ethanol blends seamlessly, making it ideal for flex-fuel platforms or dedicated alternative-fuel race cars.

The in-tank design eliminates external pump noise and heat transfer to the fuel line, keeping your fuel cooler and your engine bay cleaner—a critical advantage in tight engine compartments or weight-conscious builds. Dual 6 AN female O-ring inlet and outlet connections provide maximum flow compatibility with modern fuel rails and regulators, while the stainless steel internals resist corrosion from E85's hygroscopic nature and aggressive fuel chemistry. The included installation kit simplifies integration into existing fuel systems, and the 4.75-pound compact form factor (8.6 x 8.3 x 17.7 inches) fits most in-tank mounting locations without sacrificing fuel cell capacity. Aeromotive's reputation for precision engineering ensures low noise operation and bulletproof longevity through thousands of heat cycles and boost cycles.

This pump is the go-to choice for street-legal turbocharged builds, road-race platforms, and dedicated E85 performance vehicles where fuel system reliability is non-negotiable. If you're upgrading from a stock pump that can't support your fuel injector count or boost levels, the Phantom Stealth Flex delivers the headroom needed to prevent lean stumbles and surge issues under full throttle acceleration. Compatibility with both gasoline and E85 makes this an excellent choice for flex-fuel tuning shops and builders looking for a single solution that grows with engine modifications. Installation requires basic mechanical skill and familiarity with fuel system work; professional installation is recommended for first-time fuel pump swaps.
