Deatschwerks DW400 in-tank fuel pump Deatschwerks DW400 high-performance fuel pump DeatschWerks in-tank fuel pumps are manufactured with a quiet and reliable turbine impeller which is compatible with pulse width modulated pump drivers. These pumps are also built with carbon commutators and fully encapsulated armatures for ethanol compatibility. DWs high-torque motors maintain flow at higher pressure better than competitorspumps. Low amperage draw minimizes pump temperatures, maximizes pump life and reduces stress on OE wiring.  All DW fuel pumps are backed by a 3-year no-fault warranty.
