DSX Auxiliary Fuel Pump Kit

DSX

$1,040.00

The DSX Auxiliary Fuel Pump Kit for the 2009 - 2014 Cadillac CTS-V is a competitively-priced alternative to the expensive and difficult-to-install return-style fuel-system conversions. It is also eliminates the need to run 'boost a pump' style controllers that spike fuel pump voltage, which tax and subsequently shorten the lifespan of the factory fuel pump. With properly sized fuel injectors, this Auxiliary Fuel Pump Kit will easily support over 1,200 wheel-horsepower on gasoline, and well over 800 wheel-horsepower on e85 ethanol based fuels.

The
DSX Auxiliary Fuel Pump Kit mounts externally off your fuel tank and works in conjunction with your factory fuel pump, only when additional fuel volume is needed. The kit is centered around the-tried-and-true Bosch 044 Fuel Pump and is triggered by a unique DSX Tuning-developed pump controller, which uses the factory MAP sensor signal to trigger the pump to turn on at 7 pounds of boost. The fuel pump will also turn off at 4psi of boost. This means that the pump is passive when not in use (and thus silent), and active when additional fuel demands are required by the ECM.

The fuel pump controller also features a priming function that will run the pump for a short period of time when the key is turned on to help purge the line with new fuel. This is helpful for users that frequently change between gasoline and ethanol. This also helps to ensure the pump is primed the first time you bury the go-pedal!

The pump includes a low profile check valve on the outlet as well as a 40 micron pre-filter to help protect the pump from any debris that could potentially cause damage.

Easy electrical connectors are provided by the harness and all mounting bracketry, hardware, zipties, and safety wire are included in the kit. All fuel lines are pre-made, and a specially designed adapter make tying the 044 into the factory line an easy proposition. Push connections are utilized throughout as well.

Fuel is supplied by drilling the tank and installing the supplied 90* pipe thread AN fitting along with the included sealant. We offer (and highly recommend) the optional drill bit and thread tap for $28 to make the installation easier.

Very concise installation instructions with detailed photos are also included with each kit. Installation time for an experienced mechanic is under 2 hours. The factory fuel tank does not have to be removed, and no lift is required for installation.

This kit can be installed prior to tuning, but in order to take full advantage you will need HP Tuners or EFILive tuning software and access to a dyno / competent tuner.
