Considering a switch to EFI or swapping in that late model motor? Aeromotive's Phantom 340 Stealth Fuel System gives you the option to put a high performance fuel pump inside virtually any fuel tank, including your factory tank. Simply cut a hole in you tank. Measure the depth. Cut your pump hanger bracket to length and your baffle/basket foam. Insert the baffle. Install the retainer ring and gasket and bolt your pump and hanger down...that's it. Now you have a fuel pump inside your factory tank capable of supporting big horsepower, EFI or Carbureted, and its whisper quiet. No more welding sumps or using up trunk space with fuel cells.
