Parts for your 2014 Nissan Pulsar-Fuel cap

2014 Nissan Pulsar Fuel Cap

Yes, the 2014 Nissan Pulsar uses a conventional, screw-type fuel-filler cap. Nissan’s Owner’s Manual for the 2013–2015 Pulsar (Australia/NZ) includes explicit instructions to remove the cap by turning it anticlockwise and to tighten until it clicks, it also warns that a loose cap can trigger the Malfunction Indicator Light. The Nissan Factory Service Manual for the B17/C12 platform further notes the EVAP system relies on a properly sealing cap and can log small-leak codes (such as P0442/P0456) if the cap or seal isn’t sound. There’s no capless filler on this model.

On a 2014 Pulsar, the fuel cap’s whole job is to keep the tank sealed, clean, and compliant. It stops dust, water, and road grime sneaking into the filler neck, helps maintain the right pressure/vacuum in the tank, and keeps fuel vapours from venting to the atmosphere. That sealed system lets the EVAP gear do its thing, which is a win for emissions and for keeping the car’s diagnostic system happy. A good cap also helps avoid fuel smells around the rear quarter and can prevent evaporative losses over time.

As part of regular servicing, it’s worth giving the cap a quick once-over. Check the rubber gasket for cracks, flattening, or hard spots, and make sure the cap’s ratchet still “clicks” when you tighten it. A quick wipe of the filler neck lip with a clean rag keeps grit off the seal. If the check engine light pops on after a fill, re-seat the cap and tighten until it clicks several times, then drive a few trips to let the system re-test. Still lighting up? The cap or its seal might be due for replacement.

• Replace the cap if: the seal is perished, the tether’s broken, the cap won’t click/tighten, there’s a persistent fuel smell, or you’re seeing small EVAP leak codes after refuelling.
• Use a genuine or high-quality aftermarket cap that matches Nissan’s pressure/vacuum specs for the B17/C12 Pulsar. Cheapies that don’t seal properly can cause nuisance faults.
• At each service interval, ask the tech to inspect the cap and seal, in harsher Aussie and Kiwi climates, rubber can age quicker, so don’t be shy about swapping it every few years if it looks tired.

Popular questions

Does the 2014 Pulsar have a capless fuel filler?
No. It uses a standard screw-on fuel cap with a tether. The owner’s manual covers removing and tightening the cap and notes that a loose cap can trigger a warning light, which wouldn’t apply to a capless setup.

Why did my check engine light come on after refuelling?
Most of the time, it’s a loose or worn fuel cap causing an EVAP small-leak fault. Refit the cap and tighten until it clicks several times, then drive normally for a few trips. If the light stays on, the cap or its seal may need replacing, or there could be another EVAP leak.

How often should the fuel cap be replaced?
There’s no fixed interval, but it should be inspected at every service. Many last 5–10 years, replace sooner if the seal looks cracked or hard, if it won’t click tight, or if you notice fuel smells or recurring EVAP codes.
