Regulators

Fuel pressure regulators compatible with most fuels including petrol / E10 / E85 & Diesel (NOT methanol) and with a variety of end connections, glass/alloy bowl options and mounting accessories. Petrol King regulators are designed to improve carburetor feed, ensuring steady constant fuel flow with their wide diaphragms. A standard fuel pump can deliver a fuel pressure 5 times higher than useful to feed a carburetor, causing overload, stalling and fuel waste. Regulators can address this issue and also improve idle and aid starting.
