Product Description

The DeatschWerks 9-439-1000 is the universal-fit DW430c 430 LPH compact in-tank fuel pump with clips and universal install kit, engineered as a drop-in upgrade for fuel pump modules with a 39mm pump bore. The DW430c delivers 430 liters per hour at 40 PSI -- enough fuel volume to support 800+ horsepower on gasoline or 600+ horsepower on E85 -- in a 123mm x 39mm compact body that fits where standard-size fuel pumps don't. The advanced turbine impeller design provides quiet operation while carbon matrix commutators and an encapsulated armature deliver long-term durability with ethanol, methanol, and race fuels.

Fluid dynamics engineered to eliminate turbulence and reduce internal restrictions allow the DW430c to outflow competitors like the Walbro 255 and AEM 340 by a wide margin, with PWM compatibility for stable performance on modern ECU-controlled fuel systems. The universal install kit includes 12-gauge SLX-spec power and ground cables, a 30A in-line fuse, a 40A relay, and a relay socket with pigtails to wire the pump directly to the battery -- especially important for vehicles over 10 years old or builds making 400+ WHP where original wiring may limit voltage. Designed and manufactured in Oklahoma City, USA, and backed by DeatschWerks' industry-leading 36-month no-fault warranty.
