Why you’ll love it in your build

By stabilising fuel pressure between the pump and the carburettor, this regulator helps your needle-and-seat operate within its optimal range. Too much fuel pressure can cause flooding and choppy idle; dialing in the correct pressure improves throttle response, consistency, and real-world drivability, whether you’re cruising the street or pushing your setup on the track.

Ideal applications

Perfect for classic hot rods, street machines, and competition vehicles that rely on carburettor systems and demand precise, adjustable fuel pressure in a compact, durable regulator.
