Description

Details

Stock Subaru fuel pumps can hardly handle more power than stock, even with the stock injectors and turbo, so a larger fuel pump is a key component to making more power,, or for e85/flex fuel tuning. When the 2005 Legacy and 2008 Impreza came out, we all quickly realized the common 255lph pump upgrade was no longer a direct fit. In those early days, a lot of fuel pump assemblies were hacked up to make the pumps fit, and not always successfully.

Thankfully, Deatschworks has developed a series of higher flow, direct drop in fuel pumps for cars with more modern fuel pump assemblies.

The DW300c pump is rated at 340lph and is a direct fit for the newer fuel pump housings.

However, it is important to note that flow rate decreases with pressure, which is an important consideration with a turbocharged car. Base fuel pressure is generally 43.5 psi, and so at 20psi of boost the fuel pump is actually operating at 63.5 psi, a bit higher than the rated pressure. Fuel flow also depends on the voltage at the pump. The stock wiring can often be inadequate to provide the required amperage and voltage to meet the full flow rating.

We list all fuel pump flow rates at 13.5v and 70psi to give a more realistic figure. At these values, the dw65c will flow 275lph. This converts to 4583 cc/min, or 1145cc per injector given 4 injectors. This pump is an excellent match for 1000/1100 cc/min injectors.

This kit includes everything required (pump, fuel pump sock, o-rings) for installation on the following cars:

FRS/BRZ
2015+ WRX

E85 Compatible

Note: this pump will not significantly increase flow rate of WRX DI high pressure fuel pump and injectors.
