    Pump It Up. When it comes to a high-performance forced induction setup, like the supercharged V8 found in the 2003-2004 Ford Mustang Cobra, it’s important to have a high flowing fuel pump if upping the horsepower is desired.

The fuel pump can handle ethanol setups as well.

To make things even easier, no special wiring or splicing is required, and DeatschWerks ensures that the fuel pump will have a quiet and reliable turbine that will pump fuel for years to come.

    Warranty Information. A three-year warranty to cover any manufacturing defects is included. Check the manufacturer’s site for more details.

    Easy Installation. An installation kit is included, and it should take about an hour for the complete installation process.

    Application. The DeatschWerks 340 LPH In Tank Fuel Pump fits 2003-2004 Ford Mustang Cobra models.

    Do you need to do any wiring upgrades with these? I have a stock fuel system, and these seem like a good option. I want to avoid messing with wiring if I can though.

    What is included in the install kit ? What needs to be done to the FPDM to handle the extra voltage of the pumps ?

    What are specs on this pump besides 340LPH? Need to know voltage range and psi #.

      A nice upgrade

      After upgrading to the 03 Cobra tank and pumps on my supercharged 99 Cobra I was still running out of fuel in high rpms after upgrading to the DeatschWerks 340lph pumps I had no more problems, with plenty of room to grow.
