Fuel pressure is adjusted using the setscrew on the top. Loosen the locking nut, then use an Allen key to dial-in the desired fuel pressure, and lock down the nut to preserve the setscrew's setting.

Upton removed two major components, the passenger-side wheelwell liner and the upper intake manifold. The liner was removed so we could run the fuel lines. The upper intake manifold had to be removed to gain access to the fuel rails. Since our car was already equipped with an external fuel pump, most of the wiring was in place. Aeromotive includes detailed instructions for those who are modifying a stock Mustang.

The Stealth system is designed specifically for '86-'93 Mustangs with EFI. But don't let the designated years deter you from using a Stealth kit, as Aeromotive makes universal kits for any application. The '86-'93 tank will fit any Stang back to '79 because they share the same platform. Powell says that with some modifications to the filler neck, he believes the tank can also fit Mustangs up to '04. Aeromotive doesn't specifically make kits for those year Mustangs, nor does it make a specific kit for modular motor applications, but Powell says the catalog is very extensive and enthusiasts can build a system for virtually any application.

Using a lift and Upton's vast experience in all-things Mustang, the fuel system was installed in less than one working day. We unfortunately didn't get to fire up the car because the filler neck grommet was wasted. The A1000 pump is ready for action and thanks to it being stealthy, the pump won't be whining about working hard under boost.
