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.
