Overview

Constructed from hard-anodized aluminum, this unit allows for precise pressure adjustments to optimize engine tuning potential.
Show original supplier description
Featuring a hard-anodized aluminum body and a 33mm diaphragm, this regulator allows for pressure adjustments ranging from 2.0kgf/cm² to 8.0kgf/cm². The regulator includes four ports: a 4.5mm vacuum signal nipple on top, a 1/8 NPT fuel outlet, a 1/8 NPT fuel inlet, and a 1/8 BSPT side port for a pressure sensor or gauge. It comes with AN6 and #8 straight fittings to accommodate various fuel system setups. Please note that this unit is not compatible with E85 ethanol fuel. For high-horsepower applications or systems requiring the use of ethanol, the larger-diaphragm Type L model is recommended. This regulator is a universal-fit component, and professional installation or the addition of a separate fuel pressure gauge is highly recommended to ensure accurate system monitoring.
