A clogged fuel filter disrupts fuel flow, causing various engine problems:

Engine sputtering o r hesitation: Reduced fuel delivery leads to misfires o r lag during acceleration.

Difficulty starting: The engine may crank but fail to start due to restricted fuel flow.

Reduced fuel efficiency and power: Combustion becomes inconsistent, wasting fuel.

Potential injector o r pump damage: Prolonged fuel starvation can strain the fuel system.

Causes in Pakistan:

Use of low-quality o r contaminated diesel.

Accumulation of rust o r debris in fuel tanks.

Delayed fuel filter maintenance.

Preventive measures:

Replace fuel filters according to the manufacturer’s schedule typically every 20,000–30,000 km.

Use clean, high-quality diesel and avoid refueling from unreliable sources.

Check fuel lines and connections for leaks o r contamination.
