Four-port Carbureted Regulator MP-9433

Unlike many fuel pressure regulators that allow pressure to drop during sudden changes in fuel demand, these 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.
