The heart of the system is a DSX Tuning proprietary PnP controller that plugs into the MAP sensor. There's no need to tap vacuum lines or install a Hobbs switch as the DSX Tuning controller utilizes the electrical signal from the MAP to trigger the pump. The controller is incorporated into an easy to install harness with minimal connections to ensure the end user doesn't have to do any wiring. The pump is activated at 9psi (164kPa) and shuts off when falling below 7psi.
The DSX Tuning Aux Pump Kit is the original and budget friendly alternative to big fuel supply with a simple installation. There's no need to get inside of the factory fuel tank, as 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 system 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, so you can be sure that what you receive is the highest quality and rated for any fuel you will run through it. Don't be fooled by lower quality push lock, screw together, or plain braided hoses!
The pump is mounted under the vehicle, and all mounting hardware is supplied so the user has 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.
Installation time is roughly two hours and can be done on jack stands. It is recommended to have a low level of fuel in the tank before installation.
