Your Car’s Fuel Filler Neck Has Holes At The Top For A Reason






The fuel filling apparatus for your car is a lot more complex than we tend to give it credit for. Every time you fill up your car, it safely transports a highly flammable liquid from the pump into your gas tank (hopefully) without spilling a drop. 

If you’ve ever taken a look at the filler neck under the gas cap (or under the cover for cars without a gas cap), you’ve probably noticed some sort of hole or vent right above or around where the fuel goes in. As simple as it looks, it’s a vital part of making sure all of that gasoline and the fumes it produces are handled as safely as possible. It also ensures proper air flow when filling.

Gasoline, while sitting in your gas tank, doesn’t exist entirely as a liquid. It produces fumes. It’s part of the reason why older gas cans for yard tools like lawnmowers can puff up in hot weather. Fumes are why it’s important to make sure you’re storing your gasoline safely. Well, the gas tank in your car can act the same way if it wasn’t for those little holes in the filler neck.

All about safety

The holes, which are connected through a separate line to the fuel filler neck, vent out gasoline fumes, preventing it from building up in your gas tank. It also allows air into the gas tank. I’ve replaced gas tanks on cars before, and I’ve learned that venting is a vital part of the operation (right after I splashed myself with leftover gas from the tank of a 1999 Dodge Neon).

Tanks Inc., a company that makes aftermarket fuel tanks for custom cars and hot rods, puts it very succinctly: “You cannot put fuel into your tank unless you can get the air out… and you cannot withdraw fuel from your tank unless you can let air in.”

As with a lot of automotive features like airbags and seat belts, it’s a simple enough idea that has vast safety benefits. So the next time you’re getting gas, be sure to take a look under the gas cap. Keeping the area free of any obstructing debris is an easy thing you can do to make sure your car runs well and runs safely. After all, keeping your car clean doesn’t have any downsides.

A toolkit can go a long way toward helping you stock up on essentials. All of the major tool brands offer different kinds, including the longstanding power and hand tool favorite, Craftsman. Its products can be found in many online stores, and Amazon is currently holding a major sale. At the time of publication, a 262-piece Craftsman hand tool set is on a massive markdown of 40% off, saving you $100 at checkout.

The collection currently costs $149, which is still a lot of money, but is a big budgetary improvement over the $249 regular price. With the discount, you’re getting more for your dollar, and this kit includes 118 sockets, three ratchets to use them on, 24 wrenches, 44 hex keys, 66 specialty bits, and seven extra accessories. The set comes in a three-drawer, handled toolbox that’s part of the Craftsman VersaStack modular storage system. You’re also getting a full lifetime warranty.

While the price and quantity of tools may seem right, what is there to say about the quality of this Craftsman kit? According to most customers, it’s a worthwhile buy for any DIYer, even without a huge sale to sweeten the deal.

How online buyers feel about this Craftsman tool kit

On Amazon, the response to this specific Craftsman tool kit has been resoundingly positive. There are currently close to 300 reviews discussing this specific variant and over 10,000 for the overall product, and the vast majority gave it five stars. Most found the quality of the tools and sockets more than up to par, the VersaStack toolbox sturdy and great for organization and protection, and the price adequate. Still, it’s often said this is more of a beginner or around-the-house kind of kit, so if you want it for professional use, it’s not considered the strongest option on the market.

Elsewhere online, this kit has continued to garner largely positive press. On the Craftsman website itself, almost all of the 18 reviews gave it five stars. Some applauded the functionality of the VersaStack case and its ability to connect to other boxes in the line, while others praised the versatility of the tools within. Meanwhile, most of the 289 reviews on Lowe’s website are five-star and approve of the kit’s piece selection and durability.

There are a lot of great mechanic tool sets for anyone’s budget, and there could be a case to make that this Craftsman 262-piece set belongs alongside them. At its sale price or otherwise, it’s a hit across several retailers. Whether it’s the right set for you and your hand tool-related needs, though, is a question only you can answer.
