I was not aware of a "New" Aeromotive Stealth 340 direct drop in pump either. The DW65C is a direct drop in as is, no modification to the sending unit required pump. It is not designed to flow as much as a DW300 or Walbro 400 or Aeromotive 340. What it IS designed to do is drop in directly and provide substantially more flow than the OEM pump. For those looking to make modest power over stock and needing more fuel, this is a good, cost effective solution that wont require any additional parts to install.
