Conclusion
Something to remember is that the fuel cap isn’t just to keep rain and dirt out of the tank. It is actually a major safety item. They reduce, if not completely eliminate, the release of harmful fumes. They prevent leakage in the event of an accident and/or rollover. It is also a key part of the diagnostic and emissions systems.
A locking fuel cap does all of that, of course. But it also prevents theft and possible vandalism. By preventing anyone from tampering with your tank, with added anti-siphoning measures and fuel consumption devices you can keep a good track on fuel usage. All this will save you money in the long run.
As you can see there are numerous reasons as to why a good quality fuel cap is vital. Have you ever had issues with a bad cap? Or had your fuel stolen? What about issues with a lockable cap? Share your stories.
