Fuel Pressure Regulator

The Weldon High Performance A2040-281-A-120 fuel pressure regulator is engineered to provide precise pressure control and maintain steady fuel delivery, even during significant changes in fuel demand such as Wide Open Throttle (WOT) conditions, boost application, and gear changes. It boasts a .281" bypass orifice and a durable fluorosilicone diaphragm. Constructed from Billet Aircraft Aluminum with MIL-SPEC anodizing, this regulator is built for demanding applications. It includes two -10 pressure ports and one -8 return port, along with a 1/8" NPT gauge port and a 1/8" NPT manifold pressure reference port. The fuel pressure increases on a 1:1 ratio with boost, offering responsive control. This regulator is compatible with a wide range of fuels, including Gasoline, Methanol, Diesel, Ethanol, and most racing fuels. The adjustable pressure range is 28 to 120 PSI.
