Product Info
This system is designed to work in trucks equipped with the OEM plastic fuel tanks only; some of the 1999 models may still have a steel tank, which will not fit this Phantom series. The 1999-2004 models with a plastic tank for which this Phantom is designed use a smaller factory opening than the later 2005-2017 models, which have their own series of Phantom drop in kits.
The smaller opening in the 1999-2004 tanks does limit the pump configurations which will fit. These tanks will accommodate several pump options including; a single 340, a dual 340, and a single 450 pump. Any other combination of more/larger pumps will not physically fit through the factory tank opening.
The Silverado and Sierra tanks have a tank depth of approximately 14.00”, while the other models are shallower with depths around 8.25”. The Phantom systems will accommodate both.
The 2500 truck models can be up to 17.00” deep; the Phantom system will also accommodate this as well.
Not configured for use with the OEM, pulse-modulated-to-pressure, pump control.
Requires installation of return style fuel system including high flow AN style fuel lines, fuel filter and EFI bypass regulator with return line. Contact Aeromotive Tech Support with any questions and for more information.
This product is not legal for sale or use on emission-controlled vehicles except when used as a direct replacement part matching OEM specifications.
