    High-Performance Design. The fuel pump in your 2007-2012 Mustang GT500 is one its essential components. Proper function depends on the right fitment and the correct flow. DeatshWerks has assembled a library of over 100 different modules from which your 340 LPH In Tank Fuel Pump can be made. Each one of the seven available dimensional formats has up to four possible flow configurations to choose from.

    Construction. While not everyone is going to use E85 fuel containing up to 15% ethanol, DeatschWerks has constructed its 340 LPH In Tank Fuel Pump with that possibility in mind. Ethanol fuels can dry out the delicate components in conventional fuel pumps. The DeatschWerks 340 LPH is manufactured from a corrosion-resistant, lightweight composite. Motor armatures are fully enclosed to protect copper windings from ethanol, and carbon component damage and extends their life. The 340 LPH is subjected to Highly Accelerated Life Testing.

    Installation. No cutting or wiring required. The DeatschWerks 340 LPH In Tank Fuel Pump is a direct drop-in replacement for the factory module using the install kit included.

    Warranty. DeatschWerks has the utmost confidence in its 340 LPH In Tank Fuel Pump w/Install Kit for your 2007-2012 Mustang GT500, and this is why it backs it up with a three-year comprehensive warranty.

    Application. The DeatschWerks 340 LPH In Tank Fuel Pump w/Install Kit has been skillfully engineered, manufactured, assembled, and tested, to perform impeccably in your 2007-2012 Mustang GT500.

            DW300 Replacement Pumps

            Very nice direct replacement for the 2007-2009 GT500 dual pump set up. These pumps slip right into the mount and the wires plug in. It takes longer to remove the pumps from the tank than it does to swap the pumps.

            Great buy so far

            Did a few hits on the dyno so far dual pumps are holding up 600 rwhp/tq only running to 5700 rpm due to spark blow out due to the higher boost
