What it is & what it does

The fuel pressure regulator maintains the correct fuel pressure to the injectors so the engine gets exactly the fuel it needs across all conditions. Too much or too little pressure upsets running.

It works with the fuel pump and injectors as the fuel-delivery system.

Signs of trouble & how we help

A faulty regulator causes hard starting, rough running, poor economy, black smoke (too rich) or power loss (too lean), and sometimes a fuel smell. Confirming pressure is the key to diagnosis.

We test fuel pressure to confirm the regulator (not the pump or a leak) before replacing it.
