Magnafuel Fuel Pressure Regulator, 4-12 PSI, Inline, 10 AN O-Ring Inlet, Dual 8 AN O-Ring Outlets, 1/8" NPT Port, Aluminum, Black

Unlike many fuel pressure regulators that allow pressure to drop during sudden changes in fuel demand, MagnaFuel carbureted racing fuel pressure control units supply high performance engines with a steady diet of fuel. They feature exclusive pressure control units that control pressure drop during initial launch, gear change, or nitrous activation. They're available in 2 or 4-port configurations with 1/8 in. NPT pressure ports.
