The DeatschWerks DW420 is a 420 LPH in-tank fuel pump built for high-output and forced-induction builds that need more fuel than the factory pump can supply. This is the universal version supplied with a universal install kit so it can be adapted into a range of factory fuel modules. It is compatible with gasoline and ethanol-blend fuels.
