Description

FUELAB 525 Series fuel pressure regulators are designed with performance and flexibility in mind. They feature a return line port built inline with the inlet/outlet fittings--not on the bottom--which is great for tight spaces. The regulators accept port style and non-port style union fittings without interference. Several configurations are available, supporting carbureted applications as low as 1 psi…to fuel injected applications up to 125 psi. The regulators are compatible with gasoline, diesel, methanol, and ethanol; and feature billet aluminum construction, in your choice of anodized finishes for maximum protection. FUELAB 525 Series fuel pressure regulators use a fine thread pitch for precise pressure adjustment. Units include a 1/8 in. NPT port and plug for an external pressure gauge; and a versatile mounting bracket with stainless steel hardware is provided.
