Show original supplier description
The DeatschWerks DW300c fuel pump is engineered to deliver enhanced fuel flow with a compact design, making it an ideal upgrade for performance vehicles. The primary goal during its development was to maximize flow rate, minimize its physical footprint, and maintain the high reliability DeatschWerks is known for. Through extensive experimentation with armature configurations, the flow rate was successfully increased by 28% over the previous DW65c model, reaching a benchmark of 340LPH. Constructed with a metal and composite body, the DW300c utilizes a newly developed carbon commutator. This innovative component helps to decrease operating heat and increase the lifespan of the brushes, contributing to the pump's overall durability and performance. The result is a robust 340LPH pump that maintains the same compact footprint as the popular DW65c, ensuring compatibility with existing fuel module setups. This fuel pump is fully E85 compatible, offering flexibility for various fuel types and modifications. It is backed by a comprehensive 3-year warranty, providing peace of mind for the end-user. The DW300c is designed for a drop-in fitment in specific Subaru WRX, BRZ, and Scion FR-S models, with application-specific fitment kits included to simplify installation into the OEM fuel module.
