Most modern cars have an electric fuel pump inside the gas tank. It pushes fuel through the lines to the injectors at high pressure.
Why It Matters
Without a working pump, the engine starves for fuel and won't run.
How to Save Money on Fuel Pump Replacement
Keep your tank above a quarter full, low fuel makes the pump run hot and shortens its life
OEM pumps cost more but tend to last much longer than cheap aftermarket units
