Description

FUELAB 545 Series mini fuel pressure regulators offer all of the great benefits of the 525 Series regulators, but are smaller and 50 percent lighter! They feature a return line port built inline with the inlet/outlet fittings--not on the bottom--which is great for tight spaces; and they accept port style and non-port style union fittings without interference. Several configurations are available, supporting fuel injection applications from 10 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 545 Series mini 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.
