    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?

        • The DeatschWerks 340 lph In Tank Fuel Pump w/ Install Kit is recommended for heavily modified motors due to its high flow, however it can be used as a stock replacement.

        With this fuel pump can you use Premium fuel(93) also or just e-85?

        • This is simply E85 compatible, but E85 is not necessary. You can certainly utilize 93 octane as well.

        Will this pump work after I drop this pump in with my stock 1999 cobra and not have to do anything else?

        • This would be a direct fit upgrade replacement. We have an install guide here to reference as well. https://www.americanmuscle.com/deatschwerks-340lph-fuel-pump-9904-cust-install-393283.html

            Not a direct replacement

            This pump is not a direct replacement for a 99 GT. Not even close. Can’t use it.

            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.

            When you turn ignition you really hear it prime. powering my stroker just fine. you don't need to fully remove gas tank I only lowered my driver side and did it fine.

            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.
