    Review & Install Video

    High Performance Upgrade. Are you upgrading your New Edge Mustang to a supercharger, turbocharger or nitrous setup for big power gains? If so, don't forget about your fuel needs. The stock OEM fuel pump is fine for basic bolt-ons, but can come up short when it comes to high power applications. That is why DeatschWerks designed their In Tank Fuel Pump to deliver a generous 340 LPH (liters per hour) to support Mustangs making up to 500 or more horsepower.

    E85 Compatible. E85 is a blend of gasoline and ethanol, in any ratio up to 85 percent ethanol. E85 is inexpensive and great for making more power, but the ethanol (alcohol) content can corrode or dry out the internal components of factory fuel pumps. It is specifically because of these reasons that DeatschWerks engineered their DW300m In-Tank Fuel Pump to be compatible with E85 fuels to avoid any potential issues.

    Direct Drop In Replacement. DeatschWerks engineered their high flow Fuel Pump to be a direct drop in replacement for your Mustangs stock pump. Designed to replicate the size, geometry and electrical connectors of the original, this 340LPH Pump installs directly into the factory module with no wiring or cutting required.

    Application. This DeatschWerks 340 lph In Tank Fuel Pump with Installation Kit is specifically designed for use on 1999-2004 V6, GT, Bullitt, Mach 1 and 1999-2001 SVT Cobra Mustangs. Does not fit 2003-2004 SVT Cobra models.

    Can this replace my stock fuel pump on my stock 99 mustang cobra?

    What are the Recommended parts to go along with this item

    • This designed to work with Mustangs making 500+ HP. So it may be too much for your application if you were not making that many HP. This would pair well with supercharged or nitrous equipped vehicles.

    I'm building a naturally aspirated 5.3 big bore stroker for my 99 Cobra, I was hoping for a Max of 600 flywheel horsepower with 47lb injectors. Will this fuel pump handle that power level?

    • This fuel pump is designed to be used on Mustangs with 500 or more horsepower. This pump should easily support the 600 horsepower that you're trying to make.

      Really happy

      Purchased to replace a bad fuel pump in 2002 GT Vert, I was surprised at how much better the car ran with this pump compared to the stock pump. The car is heavily modded and I was still running the stock pump to it went. Install is a PITA removing the tank but well worth the performance.

      Great Product

      Worked as it should. Make sure (if you can) run the gas down in your tank. I had my fuel pump go bad with a full tank and the tanks are siphon-less tanks so I had to lower it enough that I could open the top and siphon from there. My pump was rather old and I changed the old fuel filter at the same time so I could definitely feel the difference.

      DeatschWerks Fuel Pump

      I had this pump installed on my 03 GT to work with my vortech V2 supercharger. and goes perfect with 42lb injectors. The car makes 400 wheel horsepower and the pump still could handle more power if wanted. great product, highly recommend if you plan on supercharging you car.

      I bought this fuel pump to replace my defective oem pump. This was a nice upgrade to compliment my edelbrock fuel rails and 30lb injectors. I won't have to worry about going lean with my 90mm intake! Easy install, simple plug and play. Great price too.

      Works great so far

      Mustang turned over but no fuel pressure. Installed the upgraded fuel pump and now she runs well again. I haven't added the turbo kit yet so cannot speak to the increased flow this pump is capable of. The item did come with a new filter for the fuel pump assembly but not a new filter for the fuel pump itself.
