Q - What is the warranty on DeatschWerks fuel pumps?

A - All DW pumps are covered by a 3-year comprehensive warranty for the original purchaser.  The only exception is the OE replacement DW100, which has a limited lifetime warranty.

Q - Are DeatschWerks fuel pumps compatible with ethanol fuels?

A - DW pumps are compatible with ethanol based fuels such as e85.  Use of ethanol based fuels will not void your warranty.  Additionally, the DW300, DW300c, and DW350iL have had special features built into their design to enhance life span when used with ethanol based fuels. 

Q - How big of a pump do I need?

A - The size of fuel pump needed depends on many different factors - power, fuel type, fuel pressure, etc.  To get an estimation of what size pump is needed, you can use our online fuel pump calculator.

Q - Can I use your pump in a Pulse-Width Modulated (PWM) application?

A - All in-tank DW fuel pumps utilize turbine impellers which are compatible with PWM controllers.  DW in-line fuel pumps are positive displacement pumps and are not compatible with PWM controllers.

Q - Can I use your pump with a Boost-A-Pump (BAP)?

A - Yes, our pumps can be used in conjunction with a BAP to increase voltage for brief periods of time to meet flow demand under full load conditions.  All of our pumps have been tested at voltages ranging from 12v to 20v.  Data of flow rates are not published, but are available upon request.  We do not recommend using voltages in excess of 20v.  We do not recommend running excess voltage for periods longer than 120 seconds.

Q - Can I run DW pumps at higher pressures?

A - Yes, DW pumps have a pressure relief valve (PRV) that opens beyond 100psi.  Do be advised that all fuel pumps, including DW decrease in flow rate as pressures increase. We provide online Flow vs Pressure data for all DW fuel pumps.

Q - How much power will a DW200, DW300, DW65c, etc. support?

A - There are several variables to account for when sizing a fuel pump for a specific horsepower figure: fuel type, fuel system pressure, voltage, etc.  To get an idea of what pump you need, we have an online fuel pump calculator available.

Q - Will your pump work with my GDI engine?

A - GDI fuel systems utilize 2 different fuel pumps, a high-pressure crank-driven pump and an in-tank lift pump.  DW pumps can be used in the fuel tank as a higher flowing upgrade to the OE in-tank lift pump.

Q - Should I hardwire my DW pump?

A - Late model, high performance applications have larger diameter fuel pump wiring, so a hardwire kit may not be necessary.  On older applications, especially those that were not originally manufactured for high power, the fuel pump wiring is often insufficient to supply a high flow fuel pump.  In these cases, a hardwire kit is a good option to get the most flow out of your DW pump.  Consult our technical support for more information.

Q - Can I install a DW pump in my car if an application-specific kit is not listed?

A - It is always recommended to use a DW application-specific kit when available.  The DW application specific kits will provide the best fitment, ease of installation, highest performance for your vehicle.  When an application specific kit is not available, our universal pump kits can usually provide the parts needed for an installation.
