FUEL SYSTEMS
| VEHICLE FUEL SYSTEM |
WHAT IS IT?
YOUR CAR'S FUEL SYSTEM WORKS WITH THE REST OF THE ENGINE
CONTROL SYSTEM TO DELIVER THE BEST PERFORMANCE WITH THE
LOWEST EMISSIONS. CHECK YOUR CAR'S FUEL SYSTEM
REGULARLY OR IMMEDIATELY IF YOU SMELL GAS OR SUSPECT A
PROBLEM.
WHAT DOES IT DO?
THE FUEL SYSTEM TRANSFERS FUEL FROM THE FUEL TANK AND
PASSES IT THROUGH A FUEL FILTER FOR CLEANING BEFORE IT
ARRIVES AT THE INJECTORS. A PRESSURE REGULATOR CONTROLS
FUEL PRESSURE TO ENSURE GOOD ENGINE PERFORMANCE UNDER
A VARIETY OF SPEED AND LOAD CONDITIONS. FUEL INJECTORS,
WHEN ACTIVATED, SPRAY A METERED AMOUNT OF FUEL INTO THE
ENGINE. COME VEHICLES USE A RETURN LINE SYSTEM TO RETURN
UNUSED FUEL BACK TO THE TANK.
