If you are looking for the original and budget friendly alternative for big fuel supply with a simple installation for your Cadillac CTS-V (V2), the DSX Tuning Aux Pump Kit is it. With this kit there is no need to get inside of the factory fuel tank because this system taps into the tank and uses an external pump that ties back into the factory feed line. With the help of the factory fuel pressure control module, the ECM always knows what your fuel pressure is even when the aux pump kicks on to give a huge boost in pressure and flow.

The DSX Tuning proprietary PnP controller that plugs into the MAP sensor is the heart of the system. The DSX Tuning controller utilizes the electrical signal from the MAP to trigger the pump so there is not a need to tap vacuum lines or install a Hobbs switch. The controller is incorporated into an easy to install harness with minimal connections to ensure that you do not have to do any wiring. The pump is activated at 9psi (164kPa) and shuts off when falling below 7psi.

The auxiliary fuel pump kit features smooth bore PTFE coated crimped fuel lines to ensure leak free operation and corrosion resistance against ethanol for the life of the vehicle as well as inhibit any fuel odor from permeating through the lines. These lines are pressure tested by the manufacturer to verify against defects. These lines are 8AN in size but use 6AN connections to allow full flow even through the fitting itself (typical 6AN lines and ends are significantly smaller internally when inserted in the hose). The filter is a custom made 74 micron filter exclusively for use with these pumps, and the one piece billet tee fitting is a true push connect piece made exclusively for this application.

The pump is mounted under the vehicle, and all mounting hardware is supplied so you have a 100% complete kit to perform the installation. These systems now feature an original DSX designed and manufactured push connect tee to simplify the installation and reduce potential leak points. Drilling the fuel tank is required for installation, and an available drill and tap is available for an extra charge.

DSX manufactured components are covered against defects in materials and workmanship for the life of the product.
