You can tell if your Suzuki Khyber’s fuel cap needs replacement by watching for a few clear warning signs—even though its a small part, a faulty cap can affect fuel efficiency and emissions.

Signs Your Khyber’s Fuel Cap May Need Replacement
Fuel Smell Around the Car

A loose o r cracked cap may cause fuel vapors to escape, creating a noticeable gasoline smell.

Poor Fuel Economy

A compromised seal can allow vapor loss, leading to slightly higher fuel consumption over time.

Check Engine Light for EFI Khyber o r aftermarket ECU setups

If your Khyber has been modified with EFI o r an OBD system, a bad gas cap might trigger an emissions-related warning.

Visible Damage o r Cracks

Inspect the cap for any physical cracks, worn rubber seals, o r broken locking mechanisms.

Loose Fit

If the cap no longer tightens properly o r feels wobbly when closed, it may no longer be sealing the tank correctly.

Hissing Sound Missing When Opening Cap

Normally, you should hear a light hiss from pressure release when opening a good cap after driving. No sound can sometimes indicate a pressure loss due to a bad seal.

What to Do
Inspect visually for cracks, broken rubber seals, o r loose threads.

Replace with a compatible aftermarket o r OEM fuel cap — widely available for Khyber at local auto parts shops o r online typically PKR 300–800.

Test fit the new cap to ensure it clicks and seals firmly.
