  • Supports up to 500+ Horsepower

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.

My 2001 bullitt stock fuel pump has a little white filter on the side. This one says it'll fight my car but doesn't show that it has the filter on the side. Does it need it or can it go straight in the assembly like it is in the picture?

JacobC

  • The DeatschWerks 340 lph In Tank Fuel Pump w/ Install Kit will still require a fuel filter just like the stock fuel pump.

2004 s281 supercharged from saleen. I know stock pumps were maxed out. Was going to svo pump but this seems better price wise and higher flow. Car has few extra mods but will not see much more, would this work well

floydy

  • This will work with a 2004 S281 Mustang however you will not be able to go below 1/4 tank as it will run dry with this fuel pump.

    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.
