Comparison Showing Improved Performance Over 255LPH Pumps

Please Note: Actual performance will vary from car to car. Please read below to understand more about fuel pump flow rates:

Understanding Fuel Pump Ratings

The flow of a pump is dependant on voltage and pressure. Generally, a performance fuel pump’s advertised flow rate is at 40psi of pressure and 13.5 volts. At this rating, the Deatschwerks 300 series fuel pump flows around 325lph, but depending on the pressure and voltage, it is completely accurate to say the pump flows 185hlph or 460lph (see the flow rate tables in the images below).

The chart above shows how well the Deatschwerks pump copes with the increasing pressures typically found in turbocharged cars, compared with the Walbro 255lph pump.

This is why it is always important to know what pressure and voltage a pump is being rated at.

More About Fuel Pump Flow and Pressure

Not all customers fully understand the dynamics of a fuel pumps flow in relation to pressure, voltage, and current. Because of this, many misconceptions and confusion can occur.

A fuel pump's flow will always drop as pressure increases, how much it drops varies from pump to pump.  This is why having detailed flow specs at different pressures is important and why Deatschwerks publish them.

The majority of customers who are in a market for a pump like the Deatschwerks 300 series pump, have turbocharged or supercharged cars (that is not to say the pump can not be used in a more mild performance car). Most of these cars will be operating in a total fuel pressure range of 60-80 psi (base fuel pressure + boost pressure), so they need to worry about what a pump will flow in their specific total pressure range.

It is almost meaningless to them what a fuel pump flows at 40psi of pressure. For example, pump A could be rated at 350lph and Pump B could be rated at 300lph, but if pump B out flows pump A at 70psi of pressure then pump B is the better choice for those running 70psi of pressure.

Voltage will also vary from set-up to set-up, which is why Deatschwerks test their pumps at different voltages. Most cars will be getting between 12-14 volts to the pump but it is popular for customers to use a product like Boost-a-pump, which raises the voltage to the pump as high as 18v. That is why flow rates are shown at different voltages.

So in short, using the common rating point of 40psi and 13.5v, the 300 series pump flows about 325lph. But knowing the full flow rates ranges and specs is important to know how the pump is going to flow in a specific cars set-up.
