Product Description

The DeatschWerks 6-1000-FRB (DWR1000) adjustable fuel pressure regulator is a robust, universal solution for high-performance EFI systems. Able to flow over 1000 LPH and withstand up to 100 psi, it's ideal for builds in the 250-1000 HP range. The precision ball-bearing adjuster provides accurate tuning (≈2 psi per turn), and the large 45 mm diaphragm ensures stable pressure under varying loads.

Designed with high-strength materials - including anodized 6061 aluminum, stainless hardware, and fiber-nitrile diaphragm - it's fully compatible with ethanol, methanol, and gas blends. Featuring dual -8AN inlets and a -6AN outlet, it easily integrates into custom fuel systems. Though no gauge or fittings are included, versions with gauge and fittings are available. Lightweight (365 g) and compact, it's engineered for versatility in engine bays where space matters.
