Additional Considerations

1.      Wiring – A 400+ LPH pump draws substantial current (16-20 amps at typical operating pressures).  Make sure your chassis wiring is up to the task of delivering this much current.  A DW hardwire kit (part number FPHWK) is an inexpensive insurance policy.

2.      Size – The DW400 is a 46mm diameter pump.  Standard in-tank pumps are 39mm diameter.  Modifications to the fuel pump module will be necessary on some applications.

3.      Universal Fitment – Unlike other DW in-tank pumps, The DW400 is not an application-specific fitment pump. 

4.      Check-valve – the DW400 does not have in internal check valve.  An in-line check valve may be necessary for easy engine starts in some applications.

DeatschWerks take a unique approach to building our high flow injectors. Other fuel injection companies offer only a couple different styles of injectors and leave fitting them up to the customer. At DeatschWerks every injector they produce is a drop-in fitment for its application. Their injectors are engineered to fit your OEM harness, OEM fuel rail and OEM manifold.

All DeatschWerks high flow fuel injectors are built using only quality OEM cores. In addition, each set is balanced to within a 2% flow variation. This means better fitment, easier tuning, and increased reliability. DeatschWerks back all of their products with a comprehensive 12-month warranty. To complement their range of high performance, drop-in fitment fuel injectors, fuel system specialists, DeatschWerks, have developed the highest flowing in-tank fuel pump yet. With a flow rate of 400 litres per hour, the DW400 pump comes with an application specific or universal fitting kit and a 3-year warranty. The pump is 100% compatible with E85 ethanol fuel.

DeatschWerks also have developed two new high flow in-tank fuel pump ranges, the DW200 series; with a lower flow rate (around 255LPH) and price compared to the DW300 and the DW65c series; a compact pump with a flow rate of around 265LPH and a more compact design. There is also the brand new DW400 series fuel pump with 415LPH Flow.
