DeatschWerks Toyota/Subaru Performance In-Tank Regulator 4.5 BAR

DeatschWerks DW-6-45-M51 is a high-performance in-tank fuel pressure regulator engineered for Toyota and Subaru applications. 

This regulator is designed to help maintain stronger fuel pressure under load, especially where higher-flowing performance pumps can expose the limits of the factory regulator. In DeatschWerks’ own installation guide, they note that depending on the application, this upgrade can raise system pressure from about 58 psi to 65 psi, helping the pump maintain pressure and flow more effectively at higher demand.

Why buyers love it:

• 4.5 BAR performance regulator designed specifically for Toyota and Subaru applications.

• Helps raise fuel pressure from roughly 58 psi to 65 psi, depending on application.

• Helps maintain pressure under higher load and with higher-flowing performance pumps.

• Direct in-tank replacement style with application-specific installation support from DeatschWerks.

• Strong fit for performance builds needing a more consistent fuel-pressure solution than the factory regulator can provide.

How to use:
This part is installed inside the factory fuel pump module in place of the OE regulator. DeatschWerks’ installation guide walks through top hat removal, center section removal, regulator replacement, and module reassembly. For best results, verify exact fitment first, follow factory procedures to remove the fuel pump assembly, lubricate the regulator O-rings during installation, and make sure the retainer tabs are fully seated during reassembly.
