Air Fuel Regulator

Afr works by intercepting the air flow sensor signal which is a pressure based map sensor in hondas and modifying that signal before feeding it to the ecu.

Air fuel regulator. Whether you ve got a stock or mildly modified pump gas engine or a 1 000 plus horsepower alcohol fed race engine we ve got the right fuel pressure regulator for the job. This modified signal will in turn cause the ecu to change the air fuel ratio based on the modified. This diaphram is used in either regulator fuel or air on the port side fuel rail for the 3 0l engines and for the fuel regulator in the port side rail for the 2 5l engines. Fuel pressure regulator blue anodized 35 70 psi chevy pontiac conversion for stock regulator each 3 part number.

The air and fuel mixture get compressed at very high pressures. This leads to the ignition of the gas mixture. Aem s bung intrudes very little into the exhaust stream to reduce back. Hks air fuel regulator afr is a device that modifies the air fuel ratio of the engine.

A fuel pressure regulator commonly fails in one of two ways. For now let s focus on installing the air fuel gauge and pressure regulator without hurting yourself or burning down the garage. When the fpr gets stuck and builds up more pressure then it should it ll cause the. Air fuel gauges get their signal from a wideband oxygen sensor.

When it fails to hold pressure it provides too little fuel to the engine causing a lean mixture low pressure condition. So if your vehicle has a diesel engine then this is a symptom that you will never see from a faulty fuel pressure regulator. We ve even got regulators for diesel powered and e85. If you learn how to test a fuel pressure regulator fpr you may save some money on repairs and get your vehicle going sooner.

Summit racing has a mammoth selection of fuel pressure regulators for carbureted and fuel injected applications. The kit comes with a new bung you weld into the existing exhaust pipe.
