The new Stealth Fuel Systems for 2005-2009 s197 Mustangs is here. No need for voltage boosters and expensive twin-pump systems. Similar to the successful Corvette and Camaro Stealth Systems, the new s197 Mustang Stealth System is a complete drop-in, single fuel pump assembly for 05-09 Mustangs. The system provides a single A1000 Fuel Pump capable of supporting big HP. The best part, it drops right into your factory tank. It still incorporates the factory jet siphon system, includes an integral 100-micron pre-pump filter and an ORB-08 return line port. Now with a true return-style system in your Mustang, you can support the power you're making without the worry of the siphon system and while maintaining your factory fuel tank. All while saving you money!
