The Raceworks In-Tank 39mm E85 EFI Fuel Pump is designed to be installed inside the fuel tank of the vehicle, which helps to reduce the noise and vibration associated with external fuel pumps. The pump itself is made from high-quality materials and is designed to withstand the harsh conditions often found in high-performance applications.

It is also designed to be a direct replacement for the standard fuel pump found in most vehicles. The fuel pump is also compatible with E85 fuel, which is a higher-octane fuel that can provide additional performance benefits.
