Details

Complementing the new Apex Phantom, Aeromotive also releases its proprietary new Phantom Bladder Baffle, which literally opens and closes the door on Phantom flow control technology. While providing a continuous, high fuel flow into the Phantom Baffle using the Apex Phantom is awesome, it?s critical to allow a large volume of fuel to flow into the baffle naturally from the surrounding tank. It is also important to keep it there. The Phantom Bladder Baffle can ensure this. Installed in the inlet passages at the base of the Phantom Bladder, the new Phantom Bladder Baffle increases the flow area into the Bladder to promote rapid fuel recovery from the surrounding tank while deploying a PTFE check ball that acts to keep that critical fuel in the bladder, preventing it from escaping during hard acceleration, cornering, and off-angle vehicle maneuvers. Aeromotive?s Phantom Bladder Baffle is constructed with CNC-machined billet aluminum valve bodies, which are then anodized and loaded with a PTFE check ball and locked in to the Phantom bladder with a PTFE retaining washer. The Phantom Bladder Baffle is designed for durability and is fully compatible with gasoline and ethanol fuels. It requires no special tools and may be used in any existing or new Phantom bladder, with the Apex Phantom, or as a stand-alone solution to slosh control. Aeromotive?s Phantom Bladder Baffle is available in sets of 4 (P/N 18020) for the standard Phantom Bladder used in the Phantom 200 and Phantom 340 pump kits, or in sets of 5 (P/N 18021) for the larger Phantom Bladder used in the Phantom Flex and Phantom Dual.
